/*
A tool definition is an object with the following key/value parameters:
action: [function(deferred, restoreSelection)]
a function that is executed on clicking on the button - this will allways be executed using ng-click and will
overwrite any ng-click value in the display attribute.
The function is passed a deferred object ($q.defer()), if this is wanted to be used `return false;` from the action and
manually call `deferred.resolve();` elsewhere to notify the editor that the action has finished.
restoreSelection is only defined if the rangy library is included and it can be called as `restoreSelection()` to restore the users
selection in the WYSIWYG editor.
display: [string]?
Optional, an HTML element to be displayed as the button. The `scope` of the button is the tool definition object with some additional functions
If set this will cause buttontext and iconclass to be ignored
class: [string]?
Optional, if set will override the taOptions.classes.toolbarButton class.
buttontext: [string]?
if this is defined it will replace the contents of the element contained in the `display` element
iconclass: [string]?
if this is defined an icon (<i>) will be appended to the `display` element with this string as it's class
tooltiptext: [string]?
Optional, a plain text description of the action, used for the title attribute of the action button in the toolbar by default.
activestate: [function(commonElement)]?
this function is called on every caret movement, if it returns true then the class taOptions.classes.toolbarButtonActive
will be applied to the `display` element, else the class will be removed
disabled: [function()]?
if this function returns true then the tool will have the class taOptions.classes.disabled applied to it, else it will be removed
Other functions available on the scope are:
name: [string]
the name of the tool, this is the first parameter passed into taRegisterTool
isDisabled: [function()]
returns true if the tool is disabled, false if it isn't
displayActiveToolClass: [function(boolean)]
returns true if the tool is 'active' in the currently focussed toolbar
onElementSelect: [Object]
This object contains the following key/value pairs and is used to trigger the ta-element-select event
element: [String]
an element name, will only trigger the onElementSelect action if the tagName of the element matches this string
filter: [function(element)]?
an optional filter that returns a boolean, if true it will trigger the onElementSelect.
action: [function(event, element, editorScope)]
the action that should be executed if the onElementSelect function runs

// keyMappings
// allow customizable keyMappings for specialized key boards or languages
//
// keyMappings provides key mappings that are attached to a given commandKeyCode.
// To modify a specific keyboard binding, simply provide function which returns true
// for the event you wish to map to.
// Or to disable a specific keyboard binding, provide a function which returns false.
// Note: 'RedoKey' and 'UndoKey' are internally bound to the redo and undo functionality.
// At present, the following commandKeyCodes are in use:
// 98, 'TabKey', 'ShiftTabKey', 105, 117, 'UndoKey', 'RedoKey'
//
// To map to an new commandKeyCode, add a new key mapping such as:
// {commandKeyCode: 'CustomKey', testForKey: function (event) {
// if (event.keyCode=57 && event.ctrlKey && !event.shiftKey && !event.altKey) return true;
// } }
// to the keyMappings. This example maps ctrl+9 to 'CustomKey'
// Then where taRegisterTool(...) is called, add a commandKeyCode: 'CustomKey' and your
// tool will be bound to ctrl+9.
//
// To disble one of the already bound commandKeyCodes such as 'RedoKey' or 'UndoKey' add:
// {commandKeyCode: 'RedoKey', testForKey: function (event) { return false; } },
// {commandKeyCode: 'UndoKey', testForKey: function (event) { return false; } },
// to disable them.
