/**
 * @ngdoc module
 * @name ngAria
 * @description
 *
 * The `ngAria` module provides support for common
 * [<abbr title="Accessible Rich Internet Applications">ARIA</abbr>](http://www.w3.org/TR/wai-aria/)
 * attributes that convey state or semantic information about the application for users
 * of assistive technologies, such as screen readers.
 *
 * ## Usage
 *
 * For ngAria to do its magic, simply include the module `ngAria` as a dependency. The following
 * directives are supported:
 * `ngModel`, `ngChecked`, `ngReadonly`, `ngRequired`, `ngValue`, `ngDisabled`, `ngShow`, `ngHide`,
 * `ngClick`, `ngDblClick`, and `ngMessages`.
 *
 * Below is a more detailed breakdown of the attributes handled by ngAria:
 *
 * | Directive                                   | Supported Attributes                                                                                |
 * |---------------------------------------------|-----------------------------------------------------------------------------------------------------|
 * | {@link ng.directive:ngModel ngModel}        | aria-checked, aria-valuemin, aria-valuemax, aria-valuenow, aria-invalid, aria-required, input roles |
 * | {@link ng.directive:ngDisabled ngDisabled}  | aria-disabled                                                                                       |
 * | {@link ng.directive:ngRequired ngRequired}  | aria-required                                                                                       |
 * | {@link ng.directive:ngChecked ngChecked}    | aria-checked                                                                                        |
 * | {@link ng.directive:ngReadonly ngReadonly}  | aria-readonly                                                                                       |
 * | {@link ng.directive:ngValue ngValue}        | aria-checked                                                                                        |
 * | {@link ng.directive:ngShow ngShow}          | aria-hidden                                                                                         |
 * | {@link ng.directive:ngHide ngHide}          | aria-hidden                                                                                         |
 * | {@link ng.directive:ngDblclick ngDblclick}  | tabindex                                                                                            |
 * | {@link module:ngMessages ngMessages}        | aria-live                                                                                           |
 * | {@link ng.directive:ngClick ngClick}        | tabindex, keydown event, button role                                                                |
 *
 * Find out more information about each directive by reading the
 * {@link guide/accessibility ngAria Developer Guide}.
 *
 * ## Example
 * Using ngDisabled with ngAria:
 * ```html
 * <md-checkbox ng-disabled="disabled">
 * ```
 * Becomes:
 * ```html
 * <md-checkbox ng-disabled="disabled" aria-disabled="true">
 * ```
 *
 * ## Disabling Specific Attributes
 * It is possible to disable individual attributes added by ngAria with the
 * {@link ngAria.$ariaProvider#config config} method. For more details, see the
 * {@link guide/accessibility Developer Guide}.
 *
 * ## Disabling `ngAria` on Specific Elements
 * It is possible to make `ngAria` ignore a specific element, by adding the `ng-aria-disable`
 * attribute on it. Note that only the element itself (and not its child elements) will be ignored.

   * @description
   * @priority 200
   *
   * The $aria service contains helper methods for applying common
   * [ARIA](http://www.w3.org/TR/wai-aria/) attributes to HTML directives.
   *
   * ngAria injects common accessibility attributes that tell assistive technologies when HTML
   * elements are enabled, selected, hidden, and more. To see how this is performed with ngAria,
   * let's review a code snippet from ngAria itself:
   *
   *```js
   * ngAriaModule.directive('ngDisabled', ['$aria', function($aria) {
   *   return $aria.$$watchExpr('ngDisabled', 'aria-disabled', nodeBlackList, false);
   * }])
   *```
   * Shown above, the ngAria module creates a directive with the same signature as the
   * traditional `ng-disabled` directive. But this ngAria version is dedicated to
   * solely managing accessibility attributes on custom elements. The internal `$aria` service is
   * used to watch the boolean attribute `ngDisabled`. If it has not been explicitly set by the
   * developer, `aria-disabled` is injected as an attribute with its value synchronized to the
   * value in `ngDisabled`.
   *
   * Because ngAria hooks into the `ng-disabled` directive, developers do not have to do
   * anything to enable this feature. The `aria-disabled` attribute is automatically managed
   * simply as a silent side-effect of using `ng-disabled` with the ngAria module.
   *
   * The full list of directives that interface with ngAria:
   * * **ngModel**
   * * **ngChecked**
   * * **ngReadonly**
   * * **ngRequired**
   * * **ngDisabled**
   * * **ngValue**
   * * **ngShow**
   * * **ngHide**
   * * **ngClick**
   * * **ngDblclick**
   * * **ngMessages**
   *
   * Read the {@link guide/accessibility ngAria Developer Guide} for a thorough explanation of each
   * directive.
   *
   *
   * ## Dependencies
   * Requires the {@link ngAria} module to be installed.

/**
 * @ngdoc service
 * @name $animateCss
 * @kind object
 *
 * @description
 * The `$animateCss` service is a useful utility to trigger customized CSS-based transitions/keyframes
 * from a JavaScript-based animation or directly from a directive. The purpose of `$animateCss` is NOT
 * to side-step how `$animate` and ngAnimate work, but the goal is to allow pre-existing animations or
 * directives to create more complex animations that can be purely driven using CSS code.
 *
 * Note that only browsers that support CSS transitions and/or keyframe animations are capable of
 * rendering animations triggered via `$animateCss` (bad news for IE9 and lower).
 *
 * ## General Use
 * Once again, `$animateCss` is designed to be used inside of a registered JavaScript animation that
 * is powered by ngAnimate. It is possible to use `$animateCss` directly inside of a directive, however,
 * any automatic control over cancelling animations and/or preventing animations from being run on
 * child elements will not be handled by AngularJS. For this to work as expected, please use `$animate` to
 * trigger the animation and then setup a JavaScript animation that injects `$animateCss` to trigger
 * the CSS animation.
 *
 * The example below shows how we can create a folding animation on an element using `ng-if`:
 *
 * ```html
 * <!-- notice the `fold-animation` CSS class -->
 * <div ng-if="onOff" class="fold-animation">
 *   This element will go BOOM
 * </div>
 * <button ng-click="onOff=true">Fold In</button>
 * ```
 *
 * Now we create the **JavaScript animation** that will trigger the CSS transition:
 *
 * ```js
 * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) {
 *   return {
 *     enter: function(element, doneFn) {
 *       var height = element[0].offsetHeight;
 *       return $animateCss(element, {
 *         from: { height:'0px' },
 *         to: { height:height + 'px' },
 *         duration: 1 // one second
 *       });
 *     }
 *   }
 * }]);
 * ```
 *
 * ## More Advanced Uses
 *
 * `$animateCss` is the underlying code that ngAnimate uses to power **CSS-based animations** behind the scenes. Therefore CSS hooks
 * like `.ng-EVENT`, `.ng-EVENT-active`, `.ng-EVENT-stagger` are all features that can be triggered using `$animateCss` via JavaScript code.
 *
 * This also means that just about any combination of adding classes, removing classes, setting styles, dynamically setting a keyframe animation,
 * applying a hardcoded duration or delay value, changing the animation easing or applying a stagger animation are all options that work with
 * `$animateCss`. The service itself is smart enough to figure out the combination of options and examine the element styling properties in order
 * to provide a working animation that will run in CSS.
 *
 * The example below showcases a more advanced version of the `.fold-animation` from the example above:
 *
 * ```js
 * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) {
 *   return {
 *     enter: function(element, doneFn) {
 *       var height = element[0].offsetHeight;
 *       return $animateCss(element, {
 *         addClass: 'red large-text pulse-twice',
 *         easing: 'ease-out',
 *         from: { height:'0px' },
 *         to: { height:height + 'px' },
 *         duration: 1 // one second
 *       });
 *     }
 *   }
 * }]);
 * ```
 *
 * Since we're adding/removing CSS classes then the CSS transition will also pick those up:
 *
 * ```css
 * /&#42; since a hardcoded duration value of 1 was provided in the JavaScript animation code,
 * the CSS classes below will be transitioned despite them being defined as regular CSS classes &#42;/
 * .red { background:red; }
 * .large-text { font-size:20px; }
 *
 * /&#42; we can also use a keyframe animation and $animateCss will make it work alongside the transition &#42;/
 * .pulse-twice {
 *   animation: 0.5s pulse linear 2;
 *   -webkit-animation: 0.5s pulse linear 2;
 * }
 *
 * @keyframes pulse {
 *   from { transform: scale(0.5); }
 *   to { transform: scale(1.5); }
 * }
 *
 * @-webkit-keyframes pulse {
 *   from { -webkit-transform: scale(0.5); }
 *   to { -webkit-transform: scale(1.5); }
 * }
 * ```
 *
 * Given this complex combination of CSS classes, styles and options, `$animateCss` will figure everything out and make the animation happen.
 *
 * ## How the Options are handled
 *
 * `$animateCss` is very versatile and intelligent when it comes to figuring out what configurations to apply to the element to ensure the animation
 * works with the options provided. Say for example we were adding a class that contained a keyframe value and we wanted to also animate some inline
 * styles using the `from` and `to` properties.
 *
 * ```js
 * var animator = $animateCss(element, {
 *   from: { background:'red' },
 *   to: { background:'blue' }
 * });
 * animator.start();
 * ```
 *
 * ```css
 * .rotating-animation {
 *   animation:0.5s rotate linear;
 *   -webkit-animation:0.5s rotate linear;
 * }
 *
 * @keyframes rotate {
 *   from { transform: rotate(0deg); }
 *   to { transform: rotate(360deg); }
 * }
 *
 * @-webkit-keyframes rotate {
 *   from { -webkit-transform: rotate(0deg); }
 *   to { -webkit-transform: rotate(360deg); }
 * }
 * ```
 *
 * The missing pieces here are that we do not have a transition set (within the CSS code nor within the `$animateCss` options) and the duration of the animation is
 * going to be detected from what the keyframe styles on the CSS class are. In this event, `$animateCss` will automatically create an inline transition
 * style matching the duration detected from the keyframe style (which is present in the CSS class that is being added) and then prepare both the transition
 * and keyframe animations to run in parallel on the element. Then when the animation is underway the provided `from` and `to` CSS styles will be applied
 * and spread across the transition and keyframe animation.
 *
 * ## What is returned
 *
 * `$animateCss` works in two stages: a preparation phase and an animation phase. Therefore when `$animateCss` is first called it will NOT actually
 * start the animation. All that is going on here is that the element is being prepared for the animation (which means that the generated CSS classes are
 * added and removed on the element). Once `$animateCss` is called it will return an object with the following properties:
 *
 * ```js
 * var animator = $animateCss(element, { ... });
 * ```
 *
 * Now what do the contents of our `animator` variable look like:
 *
 * ```js
 * {
 *   // starts the animation
 *   start: Function,
 *
 *   // ends (aborts) the animation
 *   end: Function
 * }
 * ```
 *
 * To actually start the animation we need to run `animation.start()` which will then return a promise that we can hook into to detect when the animation ends.
 * If we choose not to run the animation then we MUST run `animation.end()` to perform a cleanup on the element (since some CSS classes and styles may have been
 * applied to the element during the preparation phase). Note that all other properties such as duration, delay, transitions and keyframes are just properties
 * and that changing them will not reconfigure the parameters of the animation.
 *
 * ### runner.done() vs runner.then()
 * It is documented that `animation.start()` will return a promise object and this is true, however, there is also an additional method available on the
 * runner called `.done(callbackFn)`. The done method works the same as `.finally(callbackFn)`, however, it does **not trigger a digest to occur**.
 * Therefore, for performance reasons, it's always best to use `runner.done(callback)` instead of `runner.then()`, `runner.catch()` or `runner.finally()`
 * unless you really need a digest to kick off afterwards.
 *
 * Keep in mind that, to make this easier, ngAnimate has tweaked the JS animations API to recognize when a runner instance is returned from $animateCss
 * (so there is no need to call `runner.done(doneFn)` inside of your JavaScript animation code).
 * Check the {@link ngAnimate.$animateCss#usage animation code above} to see how this works.
 *
 * @param {DOMElement} element the element that will be animated
 * @param {object} options the animation-related options that will be applied during the animation
 *
 * * `event` - The DOM event (e.g. enter, leave, move). When used, a generated CSS class of `ng-EVENT` and `ng-EVENT-active` will be applied
 * to the element during the animation. Multiple events can be provided when spaces are used as a separator. (Note that this will not perform any DOM operation.)
 * * `structural` - Indicates that the `ng-` prefix will be added to the event class. Setting to `false` or omitting will turn `ng-EVENT` and
 * `ng-EVENT-active` in `EVENT` and `EVENT-active`. Unused if `event` is omitted.
 * * `easing` - The CSS easing value that will be applied to the transition or keyframe animation (or both).
 * * `transitionStyle` - The raw CSS transition style that will be used (e.g. `1s linear all`).
 * * `keyframeStyle` - The raw CSS keyframe animation style that will be used (e.g. `1s my_animation linear`).
 * * `from` - The starting CSS styles (a key/value object) that will be applied at the start of the animation.
 * * `to` - The ending CSS styles (a key/value object) that will be applied across the animation via a CSS transition.
 * * `addClass` - A space separated list of CSS classes that will be added to the element and spread across the animation.
 * * `removeClass` - A space separated list of CSS classes that will be removed from the element and spread across the animation.
 * * `duration` - A number value representing the total duration of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `0`
 * is provided then the animation will be skipped entirely.
 * * `delay` - A number value representing the total delay of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `true` is
 * used then whatever delay value is detected from the CSS classes will be mirrored on the elements styles (e.g. by setting delay true then the style value
 * of the element will be `transition-delay: DETECTED_VALUE`). Using `true` is useful when you want the CSS classes and inline styles to all share the same
 * CSS delay value.
 * * `stagger` - A numeric time value representing the delay between successively animated elements
 * ({@link ngAnimate#css-staggering-animations Click here to learn how CSS-based staggering works in ngAnimate.})
 * * `staggerIndex` - The numeric index representing the stagger item (e.g. a value of 5 is equal to the sixth item in the stagger; therefore when a
 *   `stagger` option value of `0.1` is used then there will be a stagger delay of `600ms`)
 * * `applyClassesEarly` - Whether or not the classes being added or removed will be used when detecting the animation. This is set by `$animate` when enter/leave/move animations are fired to ensure that the CSS classes are resolved in time. (Note that this will prevent any transitions from occurring on the classes being added and removed.)
 * * `cleanupStyles` - Whether or not the provided `from` and `to` styles will be removed once
 *    the animation is closed. This is useful for when the styles are used purely for the sake of
 *    the animation and do not have a lasting visual effect on the element (e.g. a collapse and open animation).
 *    By default this value is set to `false`.
 *
 * @return {object} an object with start and end methods and details about the animation.
 *
 * * `start` - The method to start the animation. This will return a `Promise` when called.
 * * `end` - This method will cancel the animation and remove all applied CSS classes and styles.

 * then the old image will perform a `leave` animation and the new element
 * will be inserted via an `enter` animation.

/**
 * @ngdoc module
 * @name ngAnimate
 * @description
 *
 * The `ngAnimate` module provides support for CSS-based animations (keyframes and transitions) as well as JavaScript-based animations via
 * callback hooks. Animations are not enabled by default, however, by including `ngAnimate` the animation hooks are enabled for an AngularJS app.
 *
 * ## Usage
 * Simply put, there are two ways to make use of animations when ngAnimate is used: by using **CSS** and **JavaScript**. The former works purely based
 * using CSS (by using matching CSS selectors/styles) and the latter triggers animations that are registered via `module.animation()`. For
 * both CSS and JS animations the sole requirement is to have a matching `CSS class` that exists both in the registered animation and within
 * the HTML element that the animation will be triggered on.
 *
 * ## Directive Support
 * The following directives are "animation aware":
 *
 * | Directive                                                                     | Supported Animations                                                      |

 * | {@link ngAnimate.directive:ngAnimateSwap#animations ngAnimateSwap}            | enter and leave                                                           |
 * | {@link ng.directive:ngClass#animations ngClass / {{class&#125;&#8203;&#125;}  | add and remove                                                            |

 * | {@link ng.directive:ngRepeat#animations ngRepeat}                             | enter, leave, and move                                                    |
 * | {@link ng.directive:ngShow#animations ngShow}                                 | add and remove (the `ng-hide` class)                                      |

 *
 * (More information can be found by visiting the documentation associated with each directive.)
 *
 * For a full breakdown of the steps involved during each animation event, refer to the
 * {@link ng.$animate `$animate` API docs}.
 *
 * ## CSS-based Animations
 *
 * CSS-based animations with ngAnimate are unique since they require no JavaScript code at all. By using a CSS class that we reference between our HTML
 * and CSS code we can create an animation that will be picked up by AngularJS when an underlying directive performs an operation.
 *
 * The example below shows how an `enter` animation can be made possible on an element using `ng-if`:
 *
 * ```html
 * <div ng-if="bool" class="fade">
 *    Fade me in out
 * </div>
 * <button ng-click="bool=true">Fade In!</button>
 * <button ng-click="bool=false">Fade Out!</button>
 * ```
 *
 * Notice the CSS class **fade**? We can now create the CSS transition code that references this class:
 *
 * ```css
 * /&#42; The starting CSS styles for the enter animation &#42;/
 * .fade.ng-enter {
 *   transition:0.5s linear all;
 *   opacity:0;
 * }
 *
 * /&#42; The finishing CSS styles for the enter animation &#42;/
 * .fade.ng-enter.ng-enter-active {
 *   opacity:1;
 * }
 * ```
 *
 * The key thing to remember here is that, depending on the animation event (which each of the directives above trigger depending on what's going on) two
 * generated CSS classes will be applied to the element; in the example above we have `.ng-enter` and `.ng-enter-active`. For CSS transitions, the transition
 * code **must** be defined within the starting CSS class (in this case `.ng-enter`). The destination class is what the transition will animate towards.
 *
 * If for example we wanted to create animations for `leave` and `move` (ngRepeat triggers move) then we can do so using the same CSS naming conventions:
 *
 * ```css
 * /&#42; now the element will fade out before it is removed from the DOM &#42;/
 * .fade.ng-leave {
 *   transition:0.5s linear all;
 *   opacity:1;
 * }
 * .fade.ng-leave.ng-leave-active {
 *   opacity:0;
 * }
 * ```
 *
 * We can also make use of **CSS Keyframes** by referencing the keyframe animation within the starting CSS class:
 *
 * ```css
 * /&#42; there is no need to define anything inside of the destination
 * CSS class since the keyframe will take charge of the animation &#42;/
 * .fade.ng-leave {
 *   animation: my_fade_animation 0.5s linear;
 *   -webkit-animation: my_fade_animation 0.5s linear;
 * }
 *
 * @keyframes my_fade_animation {
 *   from { opacity:1; }
 *   to { opacity:0; }
 * }
 *
 * @-webkit-keyframes my_fade_animation {
 *   from { opacity:1; }
 *   to { opacity:0; }
 * }
 * ```
 *
 * Feel free also mix transitions and keyframes together as well as any other CSS classes on the same element.
 *
 * ### CSS Class-based Animations
 *
 * Class-based animations (animations that are triggered via `ngClass`, `ngShow`, `ngHide` and some other directives) have a slightly different
 * naming convention. Class-based animations are basic enough that a standard transition or keyframe can be referenced on the class being added
 * and removed.
 *
 * For example if we wanted to do a CSS animation for `ngHide` then we place an animation on the `.ng-hide` CSS class:
 *
 * ```html
 * <div ng-show="bool" class="fade">
 *   Show and hide me
 * </div>
 * <button ng-click="bool=!bool">Toggle</button>
 *
 * <style>
 * .fade.ng-hide {
 *   transition:0.5s linear all;
 *   opacity:0;
 * }
 * </style>
 * ```
 *
 * All that is going on here with ngShow/ngHide behind the scenes is the `.ng-hide` class is added/removed (when the hidden state is valid). Since
 * ngShow and ngHide are animation aware then we can match up a transition and ngAnimate handles the rest.
 *
 * In addition the addition and removal of the CSS class, ngAnimate also provides two helper methods that we can use to further decorate the animation
 * with CSS styles.
 *
 * ```html
 * <div ng-class="{on:onOff}" class="highlight">
 *   Highlight this box
 * </div>
 * <button ng-click="onOff=!onOff">Toggle</button>
 *
 * <style>
 * .highlight {
 *   transition:0.5s linear all;
 * }
 * .highlight.on-add {
 *   background:white;
 * }
 * .highlight.on {
 *   background:yellow;
 * }
 * .highlight.on-remove {
 *   background:black;
 * }
 * </style>
 * ```
 *
 * We can also make use of CSS keyframes by placing them within the CSS classes.
 *
 *
 * ### CSS Staggering Animations
 * A Staggering animation is a collection of animations that are issued with a slight delay in between each successive operation resulting in a
 * curtain-like effect. The ngAnimate module (versions >=1.2) supports staggering animations and the stagger effect can be
 * performed by creating a **ng-EVENT-stagger** CSS class and attaching that class to the base CSS class used for
 * the animation. The style property expected within the stagger class can either be a **transition-delay** or an
 * **animation-delay** property (or both if your animation contains both transitions and keyframe animations).
 *
 * ```css
 * .my-animation.ng-enter {
 *   /&#42; standard transition code &#42;/
 *   transition: 1s linear all;
 *   opacity:0;
 * }
 * .my-animation.ng-enter-stagger {
 *   /&#42; this will have a 100ms delay between each successive leave animation &#42;/
 *   transition-delay: 0.1s;
 *
 *   /&#42; As of 1.4.4, this must always be set: it signals ngAnimate
 *     to not accidentally inherit a delay property from another CSS class &#42;/
 *   transition-duration: 0s;
 *
 *   /&#42; if you are using animations instead of transitions you should configure as follows:
 *     animation-delay: 0.1s;
 *     animation-duration: 0s; &#42;/
 * }
 * .my-animation.ng-enter.ng-enter-active {
 *   /&#42; standard transition styles &#42;/
 *   opacity:1;
 * }
 * ```
 *
 * Staggering animations work by default in ngRepeat (so long as the CSS class is defined). Outside of ngRepeat, to use staggering animations
 * on your own, they can be triggered by firing multiple calls to the same event on $animate. However, the restrictions surrounding this
 * are that each of the elements must have the same CSS className value as well as the same parent element. A stagger operation
 * will also be reset if one or more animation frames have passed since the multiple calls to `$animate` were fired.
 *
 * The following code will issue the **ng-leave-stagger** event on the element provided:
 *
 * ```js
 * var kids = parent.children();
 *
 * $animate.leave(kids[0]); //stagger index=0
 * $animate.leave(kids[1]); //stagger index=1
 * $animate.leave(kids[2]); //stagger index=2
 * $animate.leave(kids[3]); //stagger index=3
 * $animate.leave(kids[4]); //stagger index=4
 *
 * window.requestAnimationFrame(function() {
 *   //stagger has reset itself
 *   $animate.leave(kids[5]); //stagger index=0
 *   $animate.leave(kids[6]); //stagger index=1
 *
 *   $scope.$digest();
 * });
 * ```
 *
 * Stagger animations are currently only supported within CSS-defined animations.
 *
 * ### The `ng-animate` CSS class
 *
 * When ngAnimate is animating an element it will apply the `ng-animate` CSS class to the element for the duration of the animation.
 * This is a temporary CSS class and it will be removed once the animation is over (for both JavaScript and CSS-based animations).
 *
 * Therefore, animations can be applied to an element using this temporary class directly via CSS.
 *
 * ```css
 * .zipper.ng-animate {
 *   transition:0.5s linear all;
 * }
 * .zipper.ng-enter {
 *   opacity:0;
 * }
 * .zipper.ng-enter.ng-enter-active {
 *   opacity:1;
 * }
 * .zipper.ng-leave {
 *   opacity:1;
 * }
 * .zipper.ng-leave.ng-leave-active {
 *   opacity:0;
 * }
 * ```
 *
 * (Note that the `ng-animate` CSS class is reserved and it cannot be applied on an element directly since ngAnimate will always remove
 * the CSS class once an animation has completed.)
 *
 *
 * ### The `ng-[event]-prepare` class
 *
 * This is a special class that can be used to prevent unwanted flickering / flash of content before
 * the actual animation starts. The class is added as soon as an animation is initialized, but removed
 * before the actual animation starts (after waiting for a $digest).
 * It is also only added for *structural* animations (`enter`, `move`, and `leave`).
 *
 * In practice, flickering can appear when nesting elements with structural animations such as `ngIf`
 * into elements that have class-based animations such as `ngClass`.
 *
 * ```html
 * <div ng-class="{red: myProp}">
 *   <div ng-class="{blue: myProp}">
 *     <div class="message" ng-if="myProp"></div>
 *   </div>
 * </div>
 * ```
 *
 * It is possible that during the `enter` animation, the `.message` div will be briefly visible before it starts animating.
 * In that case, you can add styles to the CSS that make sure the element stays hidden before the animation starts:
 *
 * ```css
 * .message.ng-enter-prepare {
 *   opacity: 0;
 * }
 * ```
 *
 * ### Animating between value changes
 *
 * Sometimes you need to animate between different expression states, whose values
 * don't necessary need to be known or referenced in CSS styles.
 * Unless possible with another {@link ngAnimate#directive-support "animation aware" directive},
 * that specific use case can always be covered with {@link ngAnimate.directive:ngAnimateSwap} as
 * can be seen in {@link ngAnimate.directive:ngAnimateSwap#examples this example}.
 *
 * Note that {@link ngAnimate.directive:ngAnimateSwap} is a *structural directive*, which means it
 * creates a new instance of the element (including any other/child directives it may have) and
 * links it to a new scope every time *swap* happens. In some cases this might not be desirable
 * (e.g. for performance reasons, or when you wish to retain internal state on the original
 * element instance).
 *
 * ## JavaScript-based Animations
 *
 * ngAnimate also allows for animations to be consumed by JavaScript code. The approach is similar to CSS-based animations (where there is a shared
 * CSS class that is referenced in our HTML code) but in addition we need to register the JavaScript animation on the module. By making use of the
 * `module.animation()` module function we can register the animation.
 *
 * Let's see an example of a enter/leave animation using `ngRepeat`:
 *
 * ```html
 * <div ng-repeat="item in items" class="slide">
 *   {{ item }}
 * </div>
 * ```
 *
 * See the **slide** CSS class? Let's use that class to define an animation that we'll structure in our module code by using `module.animation`:
 *
 * ```js
 * myModule.animation('.slide', [function() {
 *   return {
 *     // make note that other events (like addClass/removeClass)
 *     // have different function input parameters
 *     enter: function(element, doneFn) {
 *       jQuery(element).fadeIn(1000, doneFn);
 *
 *       // remember to call doneFn so that AngularJS
 *       // knows that the animation has concluded
 *     },
 *
 *     move: function(element, doneFn) {
 *       jQuery(element).fadeIn(1000, doneFn);
 *     },
 *
 *     leave: function(element, doneFn) {
 *       jQuery(element).fadeOut(1000, doneFn);
 *     }
 *   }
 * }]);
 * ```
 *
 * The nice thing about JS-based animations is that we can inject other services and make use of advanced animation libraries such as
 * greensock.js and velocity.js.
 *
 * If our animation code class-based (meaning that something like `ngClass`, `ngHide` and `ngShow` triggers it) then we can still define
 * our animations inside of the same registered animation, however, the function input arguments are a bit different:
 *
 * ```html
 * <div ng-class="color" class="colorful">
 *   this box is moody
 * </div>
 * <button ng-click="color='red'">Change to red</button>
 * <button ng-click="color='blue'">Change to blue</button>
 * <button ng-click="color='green'">Change to green</button>
 * ```
 *
 * ```js
 * myModule.animation('.colorful', [function() {
 *   return {
 *     addClass: function(element, className, doneFn) {
 *       // do some cool animation and call the doneFn
 *     },
 *     removeClass: function(element, className, doneFn) {
 *       // do some cool animation and call the doneFn
 *     },
 *     setClass: function(element, addedClass, removedClass, doneFn) {
 *       // do some cool animation and call the doneFn
 *     }
 *   }
 * }]);
 * ```
 *
 * ## CSS + JS Animations Together
 *
 * AngularJS 1.4 and higher has taken steps to make the amalgamation of CSS and JS animations more flexible. However, unlike earlier versions of AngularJS,
 * defining CSS and JS animations to work off of the same CSS class will not work anymore. Therefore the example below will only result in **JS animations taking
 * charge of the animation**:
 *
 * ```html
 * <div ng-if="bool" class="slide">
 *   Slide in and out
 * </div>
 * ```
 *
 * ```js
 * myModule.animation('.slide', [function() {
 *   return {
 *     enter: function(element, doneFn) {
 *       jQuery(element).slideIn(1000, doneFn);
 *     }
 *   }
 * }]);
 * ```
 *
 * ```css
 * .slide.ng-enter {
 *   transition:0.5s linear all;
 *   transform:translateY(-100px);
 * }
 * .slide.ng-enter.ng-enter-active {
 *   transform:translateY(0);
 * }
 * ```
 *
 * Does this mean that CSS and JS animations cannot be used together? Do JS-based animations always have higher priority? We can make up for the
 * lack of CSS animations by using the `$animateCss` service to trigger our own tweaked-out, CSS-based animations directly from
 * our own JS-based animation code:
 *
 * ```js
 * myModule.animation('.slide', ['$animateCss', function($animateCss) {
 *   return {
 *     enter: function(element) {
*        // this will trigger `.slide.ng-enter` and `.slide.ng-enter-active`.
 *       return $animateCss(element, {
 *         event: 'enter',
 *         structural: true
 *       });
 *     }
 *   }
 * }]);
 * ```
 *
 * The nice thing here is that we can save bandwidth by sticking to our CSS-based animation code and we don't need to rely on a 3rd-party animation framework.
 *
 * The `$animateCss` service is very powerful since we can feed in all kinds of extra properties that will be evaluated and fed into a CSS transition or
 * keyframe animation. For example if we wanted to animate the height of an element while adding and removing classes then we can do so by providing that
 * data into `$animateCss` directly:
 *
 * ```js
 * myModule.animation('.slide', ['$animateCss', function($animateCss) {
 *   return {
 *     enter: function(element) {
 *       return $animateCss(element, {
 *         event: 'enter',
 *         structural: true,
 *         addClass: 'maroon-setting',
 *         from: { height:0 },
 *         to: { height: 200 }
 *       });
 *     }
 *   }
 * }]);
 * ```
 *
 * Now we can fill in the rest via our transition CSS code:
 *
 * ```css
 * /&#42; the transition tells ngAnimate to make the animation happen &#42;/
 * .slide.ng-enter { transition:0.5s linear all; }
 *
 * /&#42; this extra CSS class will be absorbed into the transition
 * since the $animateCss code is adding the class &#42;/
 * .maroon-setting { background:red; }
 * ```
 *
 * And `$animateCss` will figure out the rest. Just make sure to have the `done()` callback fire the `doneFn` function to signal when the animation is over.
 *
 * To learn more about what's possible be sure to visit the {@link ngAnimate.$animateCss $animateCss service}.
 *
 * ## Animation Anchoring (via `ng-animate-ref`)
 *
 * ngAnimate in AngularJS 1.4 comes packed with the ability to cross-animate elements between
 * structural areas of an application (like views) by pairing up elements using an attribute
 * called `ng-animate-ref`.
 *
 * Let's say for example we have two views that are managed by `ng-view` and we want to show
 * that there is a relationship between two components situated in within these views. By using the
 * `ng-animate-ref` attribute we can identify that the two components are paired together and we
 * can then attach an animation, which is triggered when the view changes.
 *
 * Say for example we have the following template code:
 *
 * ```html
 * <!-- index.html -->
 * <div ng-view class="view-animation">
 * </div>
 *
 * <!-- home.html -->
 * <a href="#/banner-page">
 *   <img src="./banner.jpg" class="banner" ng-animate-ref="banner">
 * </a>
 *
 * <!-- banner-page.html -->
 * <img src="./banner.jpg" class="banner" ng-animate-ref="banner">
 * ```
 *
 * Now, when the view changes (once the link is clicked), ngAnimate will examine the
 * HTML contents to see if there is a match reference between any components in the view
 * that is leaving and the view that is entering. It will scan both the view which is being
 * removed (leave) and inserted (enter) to see if there are any paired DOM elements that
 * contain a matching ref value.
 *
 * The two images match since they share the same ref value. ngAnimate will now create a
 * transport element (which is a clone of the first image element) and it will then attempt
 * to animate to the position of the second image element in the next view. For the animation to
 * work a special CSS class called `ng-anchor` will be added to the transported element.
 *
 * We can now attach a transition onto the `.banner.ng-anchor` CSS class and then
 * ngAnimate will handle the entire transition for us as well as the addition and removal of
 * any changes of CSS classes between the elements:
 *
 * ```css
 * .banner.ng-anchor {
 *   /&#42; this animation will last for 1 second since there are
 *          two phases to the animation (an `in` and an `out` phase) &#42;/
 *   transition:0.5s linear all;
 * }
 * ```
 *
 * We also **must** include animations for the views that are being entered and removed
 * (otherwise anchoring wouldn't be possible since the new view would be inserted right away).
 *
 * ```css
 * .view-animation.ng-enter, .view-animation.ng-leave {
 *   transition:0.5s linear all;
 *   position:fixed;
 *   left:0;
 *   top:0;
 *   width:100%;
 * }
 * .view-animation.ng-enter {
 *   transform:translateX(100%);
 * }
 * .view-animation.ng-leave,
 * .view-animation.ng-enter.ng-enter-active {
 *   transform:translateX(0%);
 * }
 * .view-animation.ng-leave.ng-leave-active {
 *   transform:translateX(-100%);
 * }
 * ```
 *
 * Now we can jump back to the anchor animation. When the animation happens, there are two stages that occur:
 * an `out` and an `in` stage. The `out` stage happens first and that is when the element is animated away
 * from its origin. Once that animation is over then the `in` stage occurs which animates the
 * element to its destination. The reason why there are two animations is to give enough time
 * for the enter animation on the new element to be ready.
 *
 * The example above sets up a transition for both the in and out phases, but we can also target the out or
 * in phases directly via `ng-anchor-out` and `ng-anchor-in`.
 *
 * ```css
 * .banner.ng-anchor-out {
 *   transition: 0.5s linear all;
 *
 *   /&#42; the scale will be applied during the out animation,
 *          but will be animated away when the in animation runs &#42;/
 *   transform: scale(1.2);
 * }
 *
 * .banner.ng-anchor-in {
 *   transition: 1s linear all;
 * }
 * ```
 *
 *
 *
 *

 *
 * ### How is the element transported?
 *
 * When an anchor animation occurs, ngAnimate will clone the starting element and position it exactly where the starting
 * element is located on screen via absolute positioning. The cloned element will be placed inside of the root element
 * of the application (where ng-app was defined) and all of the CSS classes of the starting element will be applied. The
 * element will then animate into the `out` and `in` animations and will eventually reach the coordinates and match
 * the dimensions of the destination element. During the entire animation a CSS class of `.ng-animate-shim` will be applied
 * to both the starting and destination elements in order to hide them from being visible (the CSS styling for the class
 * is: `visibility:hidden`). Once the anchor reaches its destination then it will be removed and the destination element
 * will become visible since the shim class will be removed.
 *
 * ### How is the morphing handled?
 *
 * CSS Anchoring relies on transitions and keyframes and the internal code is intelligent enough to figure out
 * what CSS classes differ between the starting element and the destination element. These different CSS classes
 * will be added/removed on the anchor element and a transition will be applied (the transition that is provided
 * in the anchor class). Long story short, ngAnimate will figure out what classes to add and remove which will
 * make the transition of the element as smooth and automatic as possible. Be sure to use simple CSS classes that
 * do not rely on DOM nesting structure so that the anchor element appears the same as the starting element (since
 * the cloned element is placed inside of root element which is likely close to the body element).
 *
 * Note that if the root element is on the `<html>` element then the cloned node will be placed inside of body.
 *
 *
 * ## Using $animate in your directive code
 *
 * So far we've explored how to feed in animations into an AngularJS application, but how do we trigger animations within our own directives in our application?
 * By injecting the `$animate` service into our directive code, we can trigger structural and class-based hooks which can then be consumed by animations. Let's
 * imagine we have a greeting box that shows and hides itself when the data changes
 *
 * ```html
 * <greeting-box active="onOrOff">Hi there</greeting-box>
 * ```
 *
 * ```js
 * ngModule.directive('greetingBox', ['$animate', function($animate) {
 *   return function(scope, element, attrs) {
 *     attrs.$observe('active', function(value) {
 *       value ? $animate.addClass(element, 'on') : $animate.removeClass(element, 'on');
 *     });
 *   });
 * }]);
 * ```
 *
 * Now the `on` CSS class is added and removed on the greeting box component. Now if we add a CSS class on top of the greeting box element
 * in our HTML code then we can trigger a CSS or JS animation to happen.
 *
 * ```css
 * /&#42; normally we would create a CSS class to reference on the element &#42;/
 * greeting-box.on { transition:0.5s linear all; background:green; color:white; }
 * ```
 *
 * The `$animate` service contains a variety of other methods like `enter`, `leave`, `animate` and `setClass`. To learn more about what's
 * possible be sure to visit the {@link ng.$animate $animate service API page}.
 *
 *
 * ## Callbacks and Promises
 *
 * When `$animate` is called it returns a promise that can be used to capture when the animation has ended. Therefore if we were to trigger
 * an animation (within our directive code) then we can continue performing directive and scope related activities after the animation has
 * ended by chaining onto the returned promise that animation method returns.
 *
 * ```js
 * // somewhere within the depths of the directive
 * $animate.enter(element, parent).then(function() {
 *   //the animation has completed
 * });
 * ```
 *
 * (Note that earlier versions of AngularJS prior to v1.4 required the promise code to be wrapped using `$scope.$apply(...)`. This is not the case
 * anymore.)
 *
 * In addition to the animation promise, we can also make use of animation-related callbacks within our directives and controller code by registering
 * an event listener using the `$animate` service. Let's say for example that an animation was triggered on our view
 * routing controller to hook into that:
 *
 * ```js
 * ngModule.controller('HomePageController', ['$animate', function($animate) {
 *   $animate.on('enter', ngViewElement, function(element) {
 *     // the animation for this route has completed
 *   }]);
 * }])
 * ```
 *
 * (Note that you will need to trigger a digest within the callback to get AngularJS to notice any scope-related changes.)

/**
 * @ngdoc module
 * @name ngMessages
 * @description
 *
 * The `ngMessages` module provides enhanced support for displaying messages within templates
 * (typically within forms or when rendering message objects that return key/value data).
 * Instead of relying on JavaScript code and/or complex ng-if statements within your form template to
 * show and hide error messages specific to the state of an input field, the `ngMessages` and
 * `ngMessage` directives are designed to handle the complexity, inheritance and priority
 * sequencing based on the order of how the messages are defined in the template.
 *
 * Currently, the ngMessages module only contains the code for the `ngMessages`, `ngMessagesInclude`
 * `ngMessage`, `ngMessageExp` and `ngMessageDefault` directives.
 *
 * ## Usage
 * The `ngMessages` directive allows keys in a key/value collection to be associated with a child element
 * (or 'message') that will show or hide based on the truthiness of that key's value in the collection. A common use
 * case for `ngMessages` is to display error messages for inputs using the `$error` object exposed by the
 * {@link ngModel ngModel} directive.
 *
 * The child elements of the `ngMessages` directive are matched to the collection keys by a `ngMessage` or
 * `ngMessageExp` directive. The value of these attributes must match a key in the collection that is provided by
 * the `ngMessages` directive.
 *
 * Consider the following example, which illustrates a typical use case of `ngMessages`. Within the form `myForm` we
 * have a text input named `myField` which is bound to the scope variable `field` using the {@link ngModel ngModel}
 * directive.
 *
 * The `myField` field is a required input of type `email` with a maximum length of 15 characters.
 *
 * ```html
 * <form name="myForm">
 *   <label>
 *     Enter text:
 *     <input type="email" ng-model="field" name="myField" required maxlength="15" />
 *   </label>
 *   <div ng-messages="myForm.myField.$error" role="alert">
 *     <div ng-message="required">Please enter a value for this field.</div>
 *     <div ng-message="email">This field must be a valid email address.</div>
 *     <div ng-message="maxlength">This field can be at most 15 characters long.</div>
 *   </div>
 * </form>
 * ```
 *
 * In order to show error messages corresponding to `myField` we first create an element with an `ngMessages` attribute
 * set to the `$error` object owned by the `myField` input in our `myForm` form.
 *
 * Within this element we then create separate elements for each of the possible errors that `myField` could have.
 * The `ngMessage` attribute is used to declare which element(s) will appear for which error - for example,
 * setting `ng-message="required"` specifies that this particular element should be displayed when there
 * is no value present for the required field `myField` (because the key `required` will be `true` in the object
 * `myForm.myField.$error`).
 *
 * ### Message order
 *
 * By default, `ngMessages` will only display one message for a particular key/value collection at any time. If more
 * than one message (or error) key is currently true, then which message is shown is determined by the order of messages
 * in the HTML template code (messages declared first are prioritised). This mechanism means the developer does not have
 * to prioritize messages using custom JavaScript code.
 *
 * Given the following error object for our example (which informs us that the field `myField` currently has both the
 * `required` and `email` errors):
 *
 * ```javascript
 * <!-- keep in mind that ngModel automatically sets these error flags -->
 * myField.$error = { required : true, email: true, maxlength: false };
 * ```
 * The `required` message will be displayed to the user since it appears before the `email` message in the DOM.
 * Once the user types a single character, the `required` message will disappear (since the field now has a value)
 * but the `email` message will be visible because it is still applicable.
 *
 * ### Displaying multiple messages at the same time
 *
 * While `ngMessages` will by default only display one error element at a time, the `ng-messages-multiple` attribute can
 * be applied to the `ngMessages` container element to cause it to display all applicable error messages at once:
 *
 * ```html
 * <!-- attribute-style usage -->
 * <div ng-messages="myForm.myField.$error" ng-messages-multiple>...</div>
 *
 * <!-- element-style usage -->
 * <ng-messages for="myForm.myField.$error" multiple>...</ng-messages>
 * ```
 *
 * ## Reusing and Overriding Messages
 * In addition to prioritization, ngMessages also allows for including messages from a remote or an inline
 * template. This allows for generic collection of messages to be reused across multiple parts of an
 * application.
 *
 * ```html
 * <script type="text/ng-template" id="error-messages">
 *   <div ng-message="required">This field is required</div>
 *   <div ng-message="minlength">This field is too short</div>
 * </script>
 *
 * <div ng-messages="myForm.myField.$error" role="alert">
 *   <div ng-messages-include="error-messages"></div>
 * </div>
 * ```
 *
 * However, including generic messages may not be useful enough to match all input fields, therefore,
 * `ngMessages` provides the ability to override messages defined in the remote template by redefining
 * them within the directive container.
 *
 * ```html
 * <!-- a generic template of error messages known as "my-custom-messages" -->
 * <script type="text/ng-template" id="my-custom-messages">
 *   <div ng-message="required">This field is required</div>
 *   <div ng-message="minlength">This field is too short</div>
 * </script>
 *
 * <form name="myForm">
 *   <label>
 *     Email address
 *     <input type="email"
 *            id="email"
 *            name="myEmail"
 *            ng-model="email"
 *            minlength="5"
 *            required />
 *   </label>
 *   <!-- any ng-message elements that appear BEFORE the ng-messages-include will
 *        override the messages present in the ng-messages-include template -->
 *   <div ng-messages="myForm.myEmail.$error" role="alert">
 *     <!-- this required message has overridden the template message -->
 *     <div ng-message="required">You did not enter your email address</div>
 *
 *     <!-- this is a brand new message and will appear last in the prioritization -->
 *     <div ng-message="email">Your email address is invalid</div>
 *
 *     <!-- and here are the generic error messages -->
 *     <div ng-messages-include="my-custom-messages"></div>
 *   </div>
 * </form>
 * ```
 *
 * In the example HTML code above the message that is set on required will override the corresponding
 * required message defined within the remote template. Therefore, with particular input fields (such
 * email addresses, date fields, autocomplete inputs, etc...), specialized error messages can be applied
 * while more generic messages can be used to handle other, more general input errors.
 *
 * ## Dynamic Messaging
 * ngMessages also supports using expressions to dynamically change key values. Using arrays and
 * repeaters to list messages is also supported. This means that the code below will be able to
 * fully adapt itself and display the appropriate message when any of the expression data changes:
 *
 * ```html
 * <form name="myForm">
 *   <label>
 *     Email address
 *     <input type="email"
 *            name="myEmail"
 *            ng-model="email"
 *            minlength="5"
 *            required />
 *   </label>
 *   <div ng-messages="myForm.myEmail.$error" role="alert">
 *     <div ng-message="required">You did not enter your email address</div>
 *     <div ng-repeat="errorMessage in errorMessages">
 *       <!-- use ng-message-exp for a message whose key is given by an expression -->
 *       <div ng-message-exp="errorMessage.type">{{ errorMessage.text }}</div>
 *     </div>
 *   </div>
 * </form>
 * ```
 *
 * The `errorMessage.type` expression can be a string value or it can be an array so
 * that multiple errors can be associated with a single error message:
 *
 * ```html
 *   <label>
 *     Email address
 *     <input type="email"
 *            ng-model="data.email"
 *            name="myEmail"
 *            ng-minlength="5"
 *            ng-maxlength="100"
 *            required />
 *   </label>
 *   <div ng-messages="myForm.myEmail.$error" role="alert">
 *     <div ng-message-exp="'required'">You did not enter your email address</div>
 *     <div ng-message-exp="['minlength', 'maxlength']">
 *       Your email must be between 5 and 100 characters long
 *     </div>
 *   </div>
 * ```
 *
 * Feel free to use other structural directives such as ng-if and ng-switch to further control
 * what messages are active and when. Be careful, if you place ng-message on the same element
 * as these structural directives, AngularJS may not be able to determine if a message is active
 * or not. Therefore it is best to place the ng-message on a child element of the structural
 * directive.
 *
 * ```html
 * <div ng-messages="myForm.myEmail.$error" role="alert">
 *   <div ng-if="showRequiredError">
 *     <div ng-message="required">Please enter something</div>
 *   </div>
 * </div>
 * ```
 *
 * ## Animations
 * If the `ngAnimate` module is active within the application then the `ngMessages`, `ngMessage` and
 * `ngMessageExp` directives will trigger animations whenever any messages are added and removed from
 * the DOM by the `ngMessages` directive.
 *
 * Whenever the `ngMessages` directive contains one or more visible messages then the `.ng-active` CSS
 * class will be added to the element. The `.ng-inactive` CSS class will be applied when there are no
 * messages present. Therefore, CSS transitions and keyframes as well as JavaScript animations can
 * hook into the animations whenever these classes are added/removed.
 *
 * Let's say that our HTML code for our messages container looks like so:
 *
 * ```html
 * <div ng-messages="myMessages" class="my-messages" role="alert">
 *   <div ng-message="alert" class="some-message">...</div>
 *   <div ng-message="fail" class="some-message">...</div>
 * </div>
 * ```
 *
 * Then the CSS animation code for the message container looks like so:
 *
 * ```css
 * .my-messages {
 *   transition:1s linear all;
 * }
 * .my-messages.ng-active {
 *   // messages are visible
 * }
 * .my-messages.ng-inactive {
 *   // messages are hidden
 * }
 * ```
 *
 * Whenever an inner message is attached (becomes visible) or removed (becomes hidden) then the enter
 * and leave animation is triggered for each particular element bound to the `ngMessage` directive.
 *
 * Therefore, the CSS code for the inner messages looks like so:
 *
 * ```css
 * .some-message {
 *   transition:1s linear all;
 * }
 *
 * .some-message.ng-enter {}
 * .some-message.ng-enter.ng-enter-active {}
 *
 * .some-message.ng-leave {}
 * .some-message.ng-leave.ng-leave-active {}
 * ```
 *
 * {@link ngAnimate See the ngAnimate docs} to learn how to use JavaScript animations or to learn
 * more about ngAnimate.
 *
 * ## Displaying a default message
 * If the ngMessages renders no inner ngMessage directive (i.e. when none of the truthy
 * keys are matched by a defined message), then it will render a default message
 * using the {@link ngMessageDefault} directive.
 * Note that matched messages will always take precedence over unmatched messages. That means
 * the default message will not be displayed when another message is matched. This is also
 * true for `ng-messages-multiple`.
 *
 * ```html
 * <div ng-messages="myForm.myField.$error" role="alert">
 *   <div ng-message="required">This field is required</div>
 *   <div ng-message="minlength">This field is too short</div>
 *   <div ng-message-default>This field has an input error</div>
 * </div>
 * ```
 *

   * @description
   * `ngMessages` is a directive that is designed to show and hide messages based on the state
   * of a key/value object that it listens on. The directive itself complements error message
   * reporting with the `ngModel` $error object (which stores a key/value state of validation errors).
   *
   * `ngMessages` manages the state of internal messages within its container element. The internal
   * messages use the `ngMessage` directive and will be inserted/removed from the page depending
   * on if they're present within the key/value object. By default, only one message will be displayed
   * at a time and this depends on the prioritization of the messages within the template. (This can
   * be changed by using the `ng-messages-multiple` or `multiple` attribute on the directive container.)
   *
   * A remote template can also be used (With {@link ngMessagesInclude}) to promote message
   * reusability and messages can also be overridden.
   *
   * A default message can also be displayed when no `ngMessage` directive is inserted, using the
   * {@link ngMessageDefault} directive.

   * @ngdoc function
   * @name ui.router.util.$resolve#resolve
   * @methodOf ui.router.util.$resolve
   *
   * @description
   * Resolves a set of invocables. An invocable is a function to be invoked via 
   * `$injector.invoke()`, and can have an arbitrary number of dependencies. 
   * An invocable can either return a value directly,
   * or a `$q` promise. If a promise is returned it will be resolved and the 
   * resulting value will be used instead. Dependencies of invocables are resolved 
   * (in this order of precedence)
   *
   * - from the specified `locals`
   * - from another invocable that is part of this `$resolve` call
   * - from an invocable that is inherited from a `parent` call to `$resolve` 
   *   (or recursively
   * - from any ancestor `$resolve` of that parent).
   *
   * The return value of `$resolve` is a promise for an object that contains 
   * (in this order of precedence)
   *
   * - any `locals` (if specified)
   * - the resolved return values of all injectables
   * - any values inherited from a `parent` call to `$resolve` (if specified)
   *
   * The promise will resolve after the `parent` promise (if any) and all promises 
   * returned by injectables have been resolved. If any invocable 
   * (or `$injector.invoke`) throws an exception, or if a promise returned by an 
   * invocable is rejected, the `$resolve` promise is immediately rejected with the 
   * same error. A rejection of a `parent` promise (if specified) will likewise be 
   * propagated immediately. Once the `$resolve` promise has been rejected, no 
   * further invocables will be called.
   * 
   * Cyclic dependencies between invocables are not permitted and will cause `$resolve`
   * to throw an error. As a special case, an injectable can depend on a parameter 
   * with the same name as the injectable, which will be fulfilled from the `parent` 
   * injectable of the same name. This allows inherited values to be decorated. 
   * Note that in this case any other injectable in the same `$resolve` with the same
   * dependency would see the decorated value, not the inherited value.
   *
   * Note that missing dependencies -- unlike cyclic dependencies -- will cause an 
   * (asynchronous) rejection of the `$resolve` promise rather than a (synchronous) 
   * exception.
   *
   * Invocables are invoked eagerly as soon as all dependencies are available. 
   * This is true even for dependencies inherited from a `parent` call to `$resolve`.
   *
   * As a special case, an invocable can be a string, in which case it is taken to 
   * be a service name to be passed to `$injector.get()`. This is supported primarily 
   * for backwards-compatibility with the `resolve` property of `$routeProvider` 
   * routes.
   *
   * @param {object} invocables functions to invoke or 
   * `$injector` services to fetch.
   * @param {object} locals  values to make available to the injectables
   * @param {object} parent  a promise returned by another call to `$resolve`.
   * @param {object} self  the `this` for the invoked methods
   * @return {object} Promise for an object that contains the resolved return value
   * of all invocables, as well as any inherited and local values.

/**
 * @ngdoc object
 * @name ui.router.util.type:UrlMatcher
 *
 * @description
 * Matches URLs against patterns and extracts named parameters from the path or the search
 * part of the URL. A URL pattern consists of a path pattern, optionally followed by '?' and a list
 * of search parameters. Multiple search parameter names are separated by '&'. Search parameters
 * do not influence whether or not a URL is matched, but their values are passed through into
 * the matched parameters returned by {@link ui.router.util.type:UrlMatcher#methods_exec exec}.
 *
 * Path parameter placeholders can be specified using simple colon/catch-all syntax or curly brace
 * syntax, which optionally allows a regular expression for the parameter to be specified:
 *
 * * `':'` name - colon placeholder
 * * `'*'` name - catch-all placeholder
 * * `'{' name '}'` - curly placeholder
 * * `'{' name ':' regexp|type '}'` - curly placeholder with regexp or type name. Should the
 *   regexp itself contain curly braces, they must be in matched pairs or escaped with a backslash.
 *
 * Parameter names may contain only word characters (latin letters, digits, and underscore) and
 * must be unique within the pattern (across both path and search parameters). For colon
 * placeholders or curly placeholders without an explicit regexp, a path parameter matches any
 * number of characters other than '/'. For catch-all placeholders the path parameter matches
 * any number of characters.
 *
 * Examples:
 *
 * * `'/hello/'` - Matches only if the path is exactly '/hello/'. There is no special treatment for
 *   trailing slashes, and patterns have to match the entire path, not just a prefix.
 * * `'/user/:id'` - Matches '/user/bob' or '/user/1234!!!' or even '/user/' but not '/user' or
 *   '/user/bob/details'. The second path segment will be captured as the parameter 'id'.
 * * `'/user/{id}'` - Same as the previous example, but using curly brace syntax.
 * * `'/user/{id:[^/]*}'` - Same as the previous example.
 * * `'/user/{id:[0-9a-fA-F]{1,8}}'` - Similar to the previous example, but only matches if the id
 *   parameter consists of 1 to 8 hex digits.
 * * `'/files/{path:.*}'` - Matches any URL starting with '/files/' and captures the rest of the
 *   path into the parameter 'path'.
 * * `'/files/*path'` - ditto.
 * * `'/calendar/{start:date}'` - Matches "/calendar/2014-11-12" (because the pattern defined
 *   in the built-in  `date` Type matches `2014-11-12`) and provides a Date object in $stateParams.start
 *
 * @param {string} pattern  The pattern to compile into a matcher.
 * @param {Object} config  A configuration object hash:
 * @param {Object=} parentMatcher Used to concatenate the pattern/config onto
 *   an existing UrlMatcher
 *
 * * `caseInsensitive` - `true` if URL matching should be case insensitive, otherwise `false`, the default value (for backward compatibility) is `false`.
 * * `strict` - `false` if matching against a URL with a trailing slash should be treated as equivalent to a URL without a trailing slash, the default value is `true`.
 *
 * @property {string} prefix  A static prefix of this pattern. The matcher guarantees that any
 *   URL matching this matcher (i.e. any string for which {@link ui.router.util.type:UrlMatcher#methods_exec exec()} returns
 *   non-null) will start with this prefix.
 *
 * @property {string} source  The pattern that was passed into the constructor
 *
 * @property {string} sourcePath  The path portion of the source property
 *
 * @property {string} sourceSearch  The search portion of the source property
 *
 * @property {string} regex  The constructed regex that will be used to match against the url when
 *   it is time to determine which url will match.
 *
 * @returns {Object}  New `UrlMatcher` object

  /**
   * @ngdoc function
   * @name ui.router.state.$stateProvider#decorator
   * @methodOf ui.router.state.$stateProvider
   *
   * @description
   * Allows you to extend (carefully) or override (at your own peril) the 
   * `stateBuilder` object used internally by `$stateProvider`. This can be used 
   * to add custom functionality to ui-router, for example inferring templateUrl 
   * based on the state name.
   *
   * When passing only a name, it returns the current (original or decorated) builder
   * function that matches `name`.
   *
   * The builder functions that can be decorated are listed below. Though not all
   * necessarily have a good use case for decoration, that is up to you to decide.
   *
   * In addition, users can attach custom decorators, which will generate new 
   * properties within the state's internal definition. There is currently no clear 
   * use-case for this beyond accessing internal states (i.e. $state.$current), 
   * however, expect this to become increasingly relevant as we introduce additional 
   * meta-programming features.
   *
   * **Warning**: Decorators should not be interdependent because the order of 
   * execution of the builder functions in non-deterministic. Builder functions 
   * should only be dependent on the state definition object and super function.
   *
   *
   * Existing builder functions and current return values:
   *
   * - **parent** `{object}` - returns the parent state object.
   * - **data** `{object}` - returns state data, including any inherited data that is not
   *   overridden by own values (if any).
   * - **url** `{object}` - returns a {@link ui.router.util.type:UrlMatcher UrlMatcher}
   *   or `null`.
   * - **navigable** `{object}` - returns closest ancestor state that has a URL (aka is 
   *   navigable).
   * - **params** `{object}` - returns an array of state params that are ensured to 
   *   be a super-set of parent's params.
   * - **views** `{object}` - returns a views object where each key is an absolute view 
   *   name (i.e. "viewName@stateName") and each value is the config object 
   *   (template, controller) for the view. Even when you don't use the views object 
   *   explicitly on a state config, one is still created for you internally.
   *   So by decorating this builder function you have access to decorating template 
   *   and controller properties.
   * - **ownParams** `{object}` - returns an array of params that belong to the state, 
   *   not including any params defined by ancestor states.
   * - **path** `{string}` - returns the full path from the root down to this state. 
   *   Needed for state activation.
   * - **includes** `{object}` - returns an object that includes every state that 
   *   would pass a `$state.includes()` test.
   *
   * @example
   * <pre>
   * // Override the internal 'views' builder with a function that takes the state
   * // definition, and a reference to the internal function being overridden:

   *       views = parent(state);
   *

   *     result[name] = config;
   *   });
   *   return result;
   * });
   *

   *     it is injected and return value it treated as dependency. If result is a promise, it is 
   *     resolved before its value is injected into controller.

   *     }</pre>
   *
   * @param {string=} stateConfig.url
   * <a id='url'></a>
   *
   *   A url fragment with optional parameters. When a state is navigated or
   *   transitioned to, the `$stateParams` service will be populated with any 
   *   parameters that were passed.
   *
   *   (See {@link ui.router.util.type:UrlMatcher UrlMatcher} `UrlMatcher`} for
   *   more details on acceptable patterns )
   *
   * examples:
   * <pre>url: "/home"
   * url: "/users/:userid"
   * url: "/books/{bookid:[a-zA-Z_-]}"
   * url: "/books/{categoryid:int}"
   * url: "/books/{publishername:string}/{categoryid:int}"
   * url: "/messages?before&after"
   * url: "/messages?{before:date}&{after:date}"
   * url: "/messages/:mailboxid?{before:date}&{after:date}"
   * </pre>
   *
   * @param {object=} stateConfig.views
   * <a id='views'></a>
   * an optional map&lt;string, object&gt; which defined multiple views, or targets views
   * manually/explicitly.
   *
   * Examples:
   *
   * Targets three named `ui-view`s in the parent state's template
   * <pre>views: {
   *     header: {
   *       controller: "headerCtrl",
   *       templateUrl: "header.html"
   *     }, body: {
   *       controller: "bodyCtrl",
   *       templateUrl: "body.html"
   *     }, footer: {
   *       controller: "footCtrl",
   *       templateUrl: "footer.html"
   *     }
   *   }</pre>
   *
   * Targets named `ui-view="header"` from grandparent state 'top''s template, and named `ui-view="body" from parent state's template.
   * <pre>views: {
   *     'header@top': {
   *       controller: "msgHeaderCtrl",
   *       templateUrl: "msgHeader.html"
   *     }, 'body': {
   *       controller: "messagesCtrl",
   *       templateUrl: "messages.html"
   *     }
   *   }</pre>
   *
   * @param {boolean=} [stateConfig.abstract=false]
   * <a id='abstract'></a>
   * An abstract state will never be directly activated,
   *   but can provide inherited properties to its common children states.
   * <pre>abstract: true</pre>
   *
   * @param {function=} stateConfig.onEnter
   * <a id='onEnter'></a>
   *
   * Callback function for when a state is entered. Good way
   *   to trigger an action or dispatch an event, such as opening a dialog.
   * If minifying your scripts, make sure to explicitly annotate this function,
   * because it won't be automatically annotated by your build tools.
   *
   * <pre>onEnter: function(MyService, $stateParams) {
   *     MyService.foo($stateParams.myParam);
   * }</pre>
   *
   * @param {function=} stateConfig.onExit
   * <a id='onExit'></a>
   *
   * Callback function for when a state is exited. Good way to
   *   trigger an action or dispatch an event, such as opening a dialog.
   * If minifying your scripts, make sure to explicitly annotate this function,
   * because it won't be automatically annotated by your build tools.
   *
   * <pre>onExit: function(MyService, $stateParams) {
   *     MyService.cleanup($stateParams.myParam);
   * }</pre>
   *
   * @param {boolean=} [stateConfig.reloadOnSearch=true]
   * <a id='reloadOnSearch'></a>
   *
   * If `false`, will not retrigger the same state
   *   just because a search/query parameter has changed (via $location.search() or $location.hash()). 
   *   Useful for when you'd like to modify $location.search() without triggering a reload.
   * <pre>reloadOnSearch: false</pre>
   *
   * @param {object=} stateConfig.data
   * <a id='data'></a>
   *
   * Arbitrary data object, useful for custom configuration.  The parent state's `data` is
   *   prototypally inherited.  In other words, adding a data property to a state adds it to
   *   the entire subtree via prototypal inheritance.
   *
   * <pre>data: {
   *     requiredRole: 'foo'
   * } </pre>
   *
   * @param {object=} stateConfig.params
   * <a id='params'></a>
   *
   * A map which optionally configures parameters declared in the `url`, or
   *   defines additional non-url parameters.  For each parameter being
   *   configured, add a configuration object keyed to the name of the parameter.
   *
   *   Each parameter configuration object may contain the following properties:
   *
   *   - ** value ** - {object|function=}: specifies the default value for this
   *     parameter.  This implicitly sets this parameter as optional.
   *
   *     When UI-Router routes to a state and no value is
   *     specified for this parameter in the URL or transition, the
   *     default value will be used instead.  If `value` is a function,
   *     it will be injected and invoked, and the return value used.
   *
   *     *Note*: `undefined` is treated as "no default value" while `null`
   *     is treated as "the default value is `null`".
   *
   *     *Shorthand*: If you only need to configure the default value of the
   *     parameter, you may use a shorthand syntax.   In the **`params`**
   *     map, instead mapping the param name to a full parameter configuration
   *     object, simply set map it to the default parameter value, e.g.:
   *
   * <pre>// define a parameter's default value
   * params: {
   *     param1: { value: "defaultValue" }
   * }
   * // shorthand default values
   * params: {
   *     param1: "defaultValue",
   *     param2: "param2Default"
   * }</pre>
   *
   *   - ** array ** - {boolean=}: *(default: false)* If true, the param value will be
   *     treated as an array of values.  If you specified a Type, the value will be
   *     treated as an array of the specified Type.  Note: query parameter values
   *     default to a special `"auto"` mode.
   *
   *     For query parameters in `"auto"` mode, if multiple  values for a single parameter
   *     are present in the URL (e.g.: `/foo?bar=1&bar=2&bar=3`) then the values
   *     are mapped to an array (e.g.: `{ foo: [ '1', '2', '3' ] }`).  However, if
   *     only one value is present (e.g.: `/foo?bar=1`) then the value is treated as single
   *     value (e.g.: `{ foo: '1' }`).
   *
   * <pre>params: {
   *     param1: { array: true }
   * }</pre>
   *
   *   - ** squash ** - {bool|string=}: `squash` configures how a default parameter value is represented in the URL when
   *     the current parameter value is the same as the default value. If `squash` is not set, it uses the
   *     configured default squash policy.
   *     (See {@link ui.router.util.$urlMatcherFactory#methods_defaultSquashPolicy `defaultSquashPolicy()`})
   *
   *   There are three squash settings:
   *
   *     - false: The parameter's default value is not squashed.  It is encoded and included in the URL
   *     - true: The parameter's default value is omitted from the URL.  If the parameter is preceeded and followed
   *       by slashes in the state's `url` declaration, then one of those slashes are omitted.
   *       This can allow for cleaner looking URLs.
   *     - `"<arbitrary string>"`: The parameter's default value is replaced with an arbitrary placeholder of  your choice.
   *
   * <pre>params: {
   *     param1: {
   *       value: "defaultId",
   *       squash: true
   * } }
   * // squash "defaultValue" to "~"
   * params: {
   *     param1: {
   *       value: "defaultValue",
   *       squash: "~"
   * } }
   * </pre>
   *
   *
   * @example
   * <pre>
   * // Some state name examples
   *
   * // stateName can be a single top-level name (must be unique).
   * $stateProvider.state("home", {});
   *
   * // Or it can be a nested state name. This state is a child of the
   * // above "home" state.
   * $stateProvider.state("home.newest", {});
   *
   * // Nest states as deeply as needed.
   * $stateProvider.state("home.newest.abc.xyz.inception", {});
   *
   * // state() returns $stateProvider, so you can chain state declarations.
   * $stateProvider
   *   .state("home", {})
   *   .state("about", {})
   *   .state("contacts", {});

     * @description
     * Convenience method for transitioning to a new state. `$state.go` calls 
     * `$state.transitionTo` internally but automatically sets options to 
     * `{ location: true, inherit: true, relative: $state.$current, notify: true }`. 
     * This allows you to easily use an absolute or relative to path and specify 
     * only the parameters you'd like to update (while letting unspecified parameters 
     * inherit from the currently active ancestor states).
     *
     * @example
     * <pre>
     * var app = angular.module('app', ['ui.router']);
     *
     * app.controller('ctrl', function ($scope, $state) {

     * @param {string} to Absolute state name or relative state path. Some examples:
     *
     * - `$state.go('contact.detail')` - will go to the `contact.detail` state
     * - `$state.go('^')` - will go to a parent state
     * - `$state.go('^.sibling')` - will go to a sibling state
     * - `$state.go('.child.grandchild')` - will go to grandchild state
     *
     * @param {object=} params A map of the parameters that will be sent to the state, 
     * will populate $stateParams. Any parameters that are not specified will be inherited from currently 
     * defined parameters. Only parameters specified in the state definition can be overridden, new 
     * parameters will be ignored. This allows, for example, going to a sibling state that shares parameters
     * specified in a parent state. Parameter inheritance only works between common ancestor states, I.e.
     * transitioning to a sibling will get you the parameters for all parents, transitioning to a child
     * will get you all current parameters, etc.
     * @param {object=} options Options object. The options are:
     *
     * - **`location`** - {boolean=true|string=} - If `true` will update the url in the location bar, if `false`
     *    will not. If string, must be `"replace"`, which will update url and also replace last history record.
     * - **`inherit`** - {boolean=true}, If `true` will inherit url parameters from current url.
     * - **`relative`** - {object=$state.$current}, When transitioning with relative path (e.g '^'), 
     *    defines which state to be relative from.
     * - **`notify`** - {boolean=true}, If `true` will broadcast $stateChangeStart and $stateChangeSuccess events.
     * - **`reload`** (v0.2.5) - {boolean=false|string|object}, If `true` will force transition even if no state or params
     *    have changed.  It will reload the resolves and views of the current state and parent states.
     *    If `reload` is a string (or state object), the state object is fetched (by name, or object reference); and \
     *    the transition reloads the resolves and views for that matched state, and all its children states.
     *
     * @returns {promise} A promise representing the state of the new transition.
     *
     * Possible success values:
     *
     * - $state.current
     *
     * <br/>Possible rejection values:
     *
     * - 'transition superseded' - when a newer transition has been started after this one
     * - 'transition prevented' - when `event.preventDefault()` has been called in a `$stateChangeStart` listener
     * - 'transition aborted' - when `event.preventDefault()` has been called in a `$stateNotFound` listener or
     *   when a `$stateNotFound` `event.retry` promise errors.

 * @requires $compile
 * @requires $controller
 * @requires $injector
 * @requires ui.router.state.$uiViewScroll
 * @requires $document
 *
 * @restrict ECA
 *
 * @description
 * The ui-view directive tells $state where to place your templates.
 *
 * @param {string=} name A view name. The name should be unique amongst the other views in the
 * same state. You can have views of the same name that live in different states.
 *
 * @param {string=} autoscroll It allows you to set the scroll behavior of the browser window
 * when a view is populated. By default, $anchorScroll is overridden by ui-router's custom scroll
 * service, {@link ui.router.state.$uiViewScroll}. This custom service let's you
 * scroll ui-view elements into view when they are populated during a state activation.
 *
 * *Note: To revert back to old [`$anchorScroll`](http://docs.angularjs.org/api/ng.$anchorScroll)
 * functionality, call `$uiViewScrollProvider.useAnchorScroll()`.*
 *
 * @param {string=} onload Expression to evaluate whenever the view updates.
 *
 * @example
 * A view can be unnamed or named.
 * <pre>
 * <!-- Unnamed -->
 * <div ui-view></div>
 *
 * <!-- Named -->
 * <div ui-view="viewName"></div>
 * </pre>
 *
 * You can only have one unnamed view within any template (or root html). If you are only using a
 * single view and it is unnamed then you can populate it like so:
 * <pre>
 * <div ui-view></div>
 * $stateProvider.state("home", {
 *   template: "<h1>HELLO!</h1>"
 * })
 * </pre>
 *
 * The above is a convenient shortcut equivalent to specifying your view explicitly with the {@link ui.router.state.$stateProvider#methods_state `views`}
 * config property, by name, in this case an empty name:
 * <pre>
 * $stateProvider.state("home", {
 *   views: {
 *     "": {
 *       template: "<h1>HELLO!</h1>"
 *     }
 *   }    
 * })
 * </pre>
 *
 * But typically you'll only use the views property if you name your view or have more than one view
 * in the same template. There's not really a compelling reason to name a view if its the only one,
 * but you could if you wanted, like so:
 * <pre>
 * <div ui-view="main"></div>
 * </pre>
 * <pre>
 * $stateProvider.state("home", {
 *   views: {
 *     "main": {
 *       template: "<h1>HELLO!</h1>"
 *     }
 *   }    
 * })
 * </pre>
 *
 * Really though, you'll use views to set up multiple views:
 * <pre>
 * <div ui-view></div>
 * <div ui-view="chart"></div>
 * <div ui-view="data"></div>
 * </pre>
 *
 * <pre>
 * $stateProvider.state("home", {
 *   views: {
 *     "": {
 *       template: "<h1>HELLO!</h1>"
 *     },
 *     "chart": {
 *       template: "<chart_thing/>"
 *     },
 *     "data": {
 *       template: "<data_thing/>"
 *     }
 *   }    
 * })
 * </pre>
 *
 * Examples for `autoscroll`:
 *
 * <pre>
 * <!-- If autoscroll present with no expression,
 *      then scroll ui-view into view -->
 * <ui-view autoscroll/>
 *
 * <!-- If autoscroll present with valid expression,
 *      then scroll ui-view into view if expression evaluates to true -->
 * <ui-view autoscroll='true'/>
 * <ui-view autoscroll='false'/>
 * <ui-view autoscroll='scopeVariable'/>
 * </pre>
 *
 * Resolve data:
 *
 * The resolved data from the state's `resolve` block is placed on the scope as `$resolve` (this
 * can be customized using [[ViewDeclaration.resolveAs]]).  This can be then accessed from the template.
 *
 * Note that when `controllerAs` is being used, `$resolve` is set on the controller instance *after* the
 * controller is instantiated.  The `$onInit()` hook can be used to perform initialization code which
 * depends on `$resolve` data.
 *
 * Example usage of $resolve in a view template
 * <pre>
 * $stateProvider.state('home', {
 *   template: '<my-component user="$resolve.user"></my-component>',
 *   resolve: {
 *     user: function(UserService) { return UserService.fetchUser(); }
 *   }
 * });
 * </pre>

 *
 * @description
 * A directive that binds a link (`<a>` tag) to a state. If the state has an associated
 * URL, the directive will automatically generate & update the `href` attribute via
 * the {@link ui.router.state.$state#methods_href $state.href()} method. Clicking
 * the link will trigger a state transition with optional parameters.
 *
 * Also middle-clicking, right-clicking, and ctrl-clicking on the link will be
 * handled natively by the browser.
 *
 * You can also use relative state paths within ui-sref, just like the relative
 * paths passed to `$state.go()`. You just need to be aware that the path is relative
 * to the state that the link lives in, in other words the state that loaded the
 * template containing the link.
 *
 * You can specify options to pass to {@link ui.router.state.$state#methods_go $state.go()}
 * using the `ui-sref-opts` attribute. Options are restricted to `location`, `inherit`,
 * and `reload`.
 *
 * @example
 * Here's an example of how you'd use ui-sref and how it would compile. If you have the
 * following template:
 * <pre>
 * <a ui-sref="home">Home</a> | <a ui-sref="about">About</a> | <a ui-sref="{page: 2}">Next page</a>
 *
 * <ul>
 *     <li ng-repeat="contact in contacts">
 *         <a ui-sref="contacts.detail({ id: contact.id })">{{ contact.name }}</a>
 *     </li>
 * </ul>
 * </pre>
 *
 * Then the compiled html would be (assuming Html5Mode is off and current state is contacts):
 * <pre>
 * <a href="#/home" ui-sref="home">Home</a> | <a href="#/about" ui-sref="about">About</a> | <a href="#/contacts?page=2" ui-sref="{page: 2}">Next page</a>
 *
 * <ul>
 *     <li ng-repeat="contact in contacts">
 *         <a href="#/contacts/1" ui-sref="contacts.detail({ id: contact.id })">Joe</a>
 *     </li>
 *     <li ng-repeat="contact in contacts">
 *         <a href="#/contacts/2" ui-sref="contacts.detail({ id: contact.id })">Alice</a>
 *     </li>
 *     <li ng-repeat="contact in contacts">
 *         <a href="#/contacts/3" ui-sref="contacts.detail({ id: contact.id })">Bob</a>
 *     </li>

/**
 * @ngdoc directive
 * @name ui.router.state.directive:ui-sref-active
 *
 * @requires ui.router.state.$state
 * @requires ui.router.state.$stateParams
 * @requires $interpolate
 *
 * @restrict A
 *
 * @description
 * A directive working alongside ui-sref to add classes to an element when the
 * related ui-sref directive's state is active, and removing them when it is inactive.
 * The primary use-case is to simplify the special appearance of navigation menus
 * relying on `ui-sref`, by having the "active" state's menu button appear different,
 * distinguishing it from the inactive menu items.
 *
 * ui-sref-active can live on the same element as ui-sref or on a parent element. The first
 * ui-sref-active found at the same level or above the ui-sref will be used.
 *
 * Will activate when the ui-sref's target state or any child state is active. If you
 * need to activate only when the ui-sref target state is active and *not* any of
 * it's children, then you will use
 * {@link ui.router.state.directive:ui-sref-active-eq ui-sref-active-eq}
 *
 * @example
 * Given the following template:
 * <pre>
 * <ul>
 *   <li ui-sref-active="active" class="item">
 *     <a href ui-sref="app.user({user: 'bilbobaggins'})">@bilbobaggins</a>
 *   </li>
 * </ul>
 * </pre>
 *
 *
 * When the app state is "app.user" (or any children states), and contains the state parameter "user" with value "bilbobaggins",
 * the resulting HTML will appear as (note the 'active' class):
 * <pre>
 * <ul>
 *   <li ui-sref-active="active" class="item active">
 *     <a ui-sref="app.user({user: 'bilbobaggins'})" href="/users/bilbobaggins">@bilbobaggins</a>
 *   </li>
 * </ul>
 * </pre>
 *
 * The class name is interpolated **once** during the directives link time (any further changes to the
 * interpolated value are ignored).
 *
 * Multiple classes may be specified in a space-separated format:
 * <pre>
 * <ul>
 *   <li ui-sref-active='class1 class2 class3'>
 *     <a ui-sref="app.user">link</a>
 *   </li>
 * </ul>
 * </pre>
 *
 * It is also possible to pass ui-sref-active an expression that evaluates
 * to an object hash, whose keys represent active class names and whose
 * values represent the respective state names/globs.
 * ui-sref-active will match if the current active state **includes** any of
 * the specified state names/globs, even the abstract ones.
 *
 * @Example
 * Given the following template, with "admin" being an abstract state:
 * <pre>
 * <div ui-sref-active="{'active': 'admin.*'}">
 *   <a ui-sref-active="active" ui-sref="admin.roles">Roles</a>
 * </div>
 * </pre>
 *
 * When the current state is "admin.roles" the "active" class will be applied
 * to both the <div> and <a> elements. It is important to note that the state
 * names/globs passed to ui-sref-active shadow the state provided by ui-sref.
