* @overview
*
* Phaser - http://www.phaser.io
*
* v2.0.1 "Lyrelle" - Built: Mon Mar 24 2014 12:12:46
*
* By Richard Davey http://www.photonstorm.com @photonstorm
*
* Phaser is a fun, free and fast 2D game framework for making HTML5 games
* for desktop and mobile web browsers, supporting Canvas and WebGL.
*
* Phaser uses Pixi.js for rendering, created by Mat Groves http://matgroves.com @Doormat23
* Phaser uses p2.js for full-body physics, created by Stefan Hedman https://github.com/schteppe/p2.js @schteppe
* Phaser contains a port of N+ Physics, converted by Richard Davey, original by http://www.metanetsoftware.com
*
* Many thanks to Adam Saltsman (@ADAMATOMIC) for releasing Flixel, from which both Phaser
* and my love of framework development can be traced.
*
* Follow development at http://phaser.io and on our forum

* @class Phaser.Button
*
* @classdesc Create a new `Button` object. A Button is a special type of Sprite that is set-up to handle Pointer events automatically. The four states a Button responds to are:
*
* * 'Over' - when the Pointer moves over the Button. This is also commonly known as 'hover'.
* * 'Out' - when the Pointer that was previously over the Button moves out of it.
* * 'Down' - when the Pointer is pressed down on the Button. I.e. touched on a touch enabled device or clicked with the mouse.
* * 'Up' - when the Pointer that was pressed down on the Button is released again.
*
* You can set a unique texture frame and Sound for any of these states.
*
* @constructor
* @extends Phaser.Image
*
* @param {Phaser.Game} game Current game instance.
* @param {number} [x=0] - X position of the Button.
* @param {number} [y=0] - Y position of the Button.
* @param {string} [key] - The image key as defined in the Game.Cache to use as the texture for this Button.
* @param {function} [callback] - The function to call when this Button is pressed.
* @param {object} [callbackContext] - The context in which the callback will be called (usually 'this').
* @param {string|number} [overFrame] - This is the frame or frameName that will be set when this button is in an over state. Give either a number to use a frame ID or a string for a frame name.
* @param {string|number} [outFrame] - This is the frame or frameName that will be set when this button is in an out state. Give either a number to use a frame ID or a string for a frame name.
* @param {string|number} [downFrame] - This is the frame or frameName that will be set when this button is in a down state. Give either a number to use a frame ID or a string for a frame name.
* @param {string|number} [upFrame] - This is the frame or frameName that will be set when this button is in an up state. Give either a number to use a frame ID or a string for a frame name.
