/**
* Creature is a custom Game Object used in conjunction with the Creature Runtime libraries by Kestrel Moon Studios.
* 
* It allows you to display animated Game Objects that were created with the [Creature Automated Animation Tool](http://www.kestrelmoon.com/creature/).
* 
* Note 1: You can only use Phaser.Creature objects in WebGL enabled games. They do not work in Canvas mode games.
*
* Note 2: You must use a build of Phaser that includes the Creature runtimes, or have them loaded before your Phaser game boots. 
* See the Phaser custom build process for more details. By default the Creature runtimes are NOT included in any pre-configured version of Phaser.
* So you'll need to do `grunt custom` to specify a build that includes them.
*

* @extends PIXI.DisplayObjectContainer
* @extends Phaser.Component.Core

* @extends Phaser.Component.AutoCull

* @constructor
* @param {Phaser.Game} game - A reference to the currently running game.
* @param {CreatureManager} manager - A reference to the CreatureManager instance.
* @param {number} x - The x coordinate of the Game Object. The coordinate is relative to any parent container this Game Object may be in.
* @param {number} y - The y coordinate of the Game Object. The coordinate is relative to any parent container this Game Object may be in.
* @param {string|PIXI.Texture} key - The texture used by the Creature Object during rendering. It can be a string which is a reference to the Cache entry, or an instance of a PIXI.Texture.
