* Phaser SpriteBatch constructor.
*
* @classdesc The SpriteBatch class is a really fast version of the DisplayObjectContainer built solely for speed, so use when you need a lot of sprites or particles.
* @class Phaser.SpriteBatch
* @extends Phaser.Group
* @constructor
* @param {Phaser.Game} game - A reference to the currently running game.
* @param {Phaser.Group|Phaser.Sprite} parent - The parent Group, DisplayObject or DisplayObjectContainer that this Group will be added to. If undefined or null it will use game.world.
* @param {string} [name=group] - A name for this Group. Not used internally but useful for debugging.
* @param {boolean} [addToStage=false] - If set to true this Group will be added directly to the Game.Stage instead of Game.World.
