(function () {
/*\
* Raphael
[ method ]
**
* Creates a canvas object on which to draw.
* You must do this first, as all future calls to drawing methods
* from this instance will be bound to this canvas.
> Parameters
**
- 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
* or
- x (number)
- y (number)
- 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`.
= (object) @Paper

* If you want to leave no trace of Raphaël (Well, Raphaël creates only one global variable `Raphael`, but anyway.) You can use `ninja` method.
* Beware, that in this case plugins could stop working, because they are depending on global variable existance.

* You can add your own method to elements and sets. It is wise to add a set method for each element method
* you added, so you will be able to call the same method on sets too.
