* Game constructor

* providing quick access to common functions and handling the boot process.
* "Hell, there are no rules here - we're trying to accomplish something."
* Thomas A. Edison
* @constructor
* @param {number} [width=800] - The width of your game in game pixels.
* @param {number} [height=600] - The height of your game in game pixels.
* @param {number} [renderer=Phaser.AUTO] - Which renderer to use: Phaser.AUTO will auto-detect, Phaser.WEBGL, Phaser.CANVAS or Phaser.HEADLESS (no rendering at all).
* @param {string|HTMLElement} [parent=''] - The DOM element into which this games canvas will be injected. Either a DOM ID (string) or the element itself.
* @param {object} [state=null] - The default state object. A object consisting of Phaser.State functions (preload, create, update, render) or null.
* @param {boolean} [transparent=false] - Use a transparent canvas background or not.
* @param {boolean} [antialias=true] - Draw all image textures anti-aliased or not. The default is for smooth textures, but disable if your game features pixel art.
* @param {object} [physicsConfig=null] - A physics configuration object to pass to the Physics world on creation.
