A Naive NFA Implementation
Start state is always named 'start'
@param {NFAConfig|CompactNFAConfig} a
type NFAConfig = {compact:false,accepts:StateSet,trans:[Transition]}
type State = String
type StateSet = [State]
type Tranisition = {from:StateSet,to:StateSet,charset:Charset,action:Action,assert:Assert}
type Charset = String|[Range]
Charset is similar to regex charset,supports negation and range but metacharacters
Examples:
includes: 'abc0-9','[^]'
excludes: '^c-z0-9','^a^' //excluded 'a' and '^' two chars
any char: '\0-\uffff'
Or set charset to processed disjoint ranges:['ac','d','eh']
Set `charset` to empty string to enable empty move(ε-moves).
Action:
Function(stack:Array,c:String,i:Int,state:String,inputs:String):Array
stack: storage stack
c: current char
i: current index
state: current state
inputs: whole input string
Optional return new stack
Only eMove transition allow `assert`
Actions and Asserts of eMove transition always execute before non-eMove transitions on current path.
Assert:
Function(stack:Array,c:String,i:Int,state:String,inputs:String):Boolean
Return True if assertion just success,if fail return false
If success and need skip num chars,
return the Int count to increase `i`,this feature is designed for backref.
Stack modifications in action only allow shift,unshift and return new stack.
NFAConfig example used to recognize numbers:{
compact:false,accepts:'start'.
trans:[{from:'start',to:'start',charset:'0-9'}]
}
CompactNFAConfig example,see `structure` function.

compact:true,accepts:'start',

See:https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/RegExp
\0 Matches a NUL character. Do not follow this with another digit.
ECMA-262 Standard: 15.10.2.11 DecimalEscape
NOTE
If \ is followed by a decimal number n whose first digit is not 0, then the escape sequence is considered to be
a backreference. It is an error if n is greater than the total number of left capturing parentheses in the entire regular
expression. \0 represents the <NUL> character and cannot be followed by a decimal digit.
But in both Chrome and Firefox, /\077/ matches "\077",e.g. String.fromCharCode(parseInt("77",8))
/(g)\1/ matches "gg",it's OK.
But /(g)\14/ matches "g\14","\14" is String.fromCharCode(parseInt("14",8))
And /(g)\1456/ matches "g\145"+"6",/(g)\19/ matches "g\1"+"9". Who knows WTF?
Considering that ECMAScript StrictMode did not support OctEscape,
I'm not going to implement OctEscape.
I will make it conform the Standard.(Also keep code simple)

**
- container (HTMLElement|string) DOM element or its ID which is going to be a parent for drawing surface
- width (number)
- height (number)
- callback (function) #optional callback function which is going to be executed in the context of newly created paper

- width (number)
- height (number)
- callback (function) #optional callback function which is going to be executed in the context of newly created paper
* or
- all (array) (first 3 or 4 elements in the array are equal to [containerID, width, height] or [x, y, width, height]. The rest are element descriptions in format {type: type, <attributes>}). See @Paper.add.
- callback (function) #optional callback function which is going to be executed in the context of newly created paper
* or
- onReadyCallback (function) function that is going to be called on DOM ready event. You can also subscribe to this event via Eve’s “DOMLoad” event. In this case method returns `undefined`.

| // Canvas is created at the viewport’s 10,50 coordinate.
| var paper = Raphael(10, 50, 320, 200);
| // Canvas is created at the top left corner of the #notepad element

| // Same as above

/*\
* Element.transform
[ method ]
**
* Adds transformation to the element which is separate to other attributes,
* i.e. translation doesn’t change `x` or `y` of the rectange. The format
* of transformation string is similar to the path string syntax:
| "t100,100r30,100,100s2,2,100,100r45s1.5"
* Each letter is a command. There are four commands: `t` is for translate, `r` is for rotate, `s` is for
* scale and `m` is for matrix.
*
* There are also alternative “absolute” translation, rotation and scale: `T`, `R` and `S`. They will not take previous transformation into account. For example, `...T100,0` will always move element 100 px horisontally, while `...t100,0` could move it vertically if there is `r90` before. Just compare results of `r90t100,0` and `r90T100,0`.
*
* So, the example line above could be read like “translate by 100, 100; rotate 30° around 100, 100; scale twice around 100, 100;
* rotate 45° around centre; scale 1.5 times relative to centre”. As you can see rotate and scale commands have origin
* coordinates as optional parameters, the default is the centre point of the element.
* Matrix accepts six parameters.

> Colour Parsing
# <ul>
# <li>Colour name (“<code>red</code>”, “<code>green</code>”, “<code>cornflowerblue</code>”, etc)</li>
# <li>#••• — shortened HTML colour: (“<code>#000</code>”, “<code>#fc0</code>”, etc)</li>
# <li>#•••••• — full length HTML colour: (“<code>#000000</code>”, “<code>#bd2300</code>”)</li>
# <li>rgb(•••, •••, •••) — red, green and blue channels’ values: (“<code>rgb(200, 100, 0)</code>”)</li>
# <li>rgb(•••%, •••%, •••%) — same as above, but in %: (“<code>rgb(100%, 175%, 0%)</code>”)</li>
# <li>rgba(•••, •••, •••, •••) — red, green and blue channels’ values: (“<code>rgba(200, 100, 0, .5)</code>”)</li>
# <li>rgba(•••%, •••%, •••%, •••%) — same as above, but in %: (“<code>rgba(100%, 175%, 0%, 50%)</code>”)</li>
# <li>hsb(•••, •••, •••) — hue, saturation and brightness values: (“<code>hsb(0.5, 0.25, 1)</code>”)</li>
# <li>hsb(•••%, •••%, •••%) — same as above, but in %</li>
# <li>hsba(•••, •••, •••, •••) — same as above, but with opacity</li>
# <li>hsl(•••, •••, •••) — almost the same as hsb, see <a href="http://en.wikipedia.org/wiki/HSL_and_HSV" title="HSL and HSV - Wikipedia, the free encyclopedia">Wikipedia page</a></li>
# <li>hsl(•••%, •••%, •••%) — same as above, but in %</li>
# <li>hsla(•••, •••, •••, •••) — same as above, but with opacity</li>
# <li>Optionally for hsb and hsl you could specify hue as a degree: “<code>hsl(240deg, 1, .5)</code>” or, if you want to go fancy, “<code>hsl(240°, 1, .5)</code>”</li>
