* @overview
*
* Phaser - http://phaser.io
*
* v2.2.0 "Bethal" - Built: Sat Nov 15 2014 20:03:34
*
* 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 rendering.
*
* 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 originate.
*
* Follow development at http://phaser.io and on our forum
