[name]
		This class animates an object based on an hierarchy. This hierarchy can be Object3ds or bones.
		Constructor
		[name]([page:Object3d root], [page:String name])
		
		root -- The mesh to animate. 
		name -- The name of the animation
		
		
		Creates an animation for root. The animation data is gathered from AnimationHandler based on its name.
		
		Properties
		[property:Object3d root]
		
		The root object of the animation.
		
		[property:Object data]
		
		The data containing the animation
		
		[property:Array hierarchy]
		
		The objects that are influenced by the animation.
		
		[property:number currentTime]
		
		The time elapsed since the last start/restart of the animation.
		
		[property:number timeScale]
		
		How much to scale the speed of the animation. Defaults to 1.
		
		[property:boolean isPlaying]
		
		Indicates whether the animation is playing. This shouldn't be adapted by user code.
		
		[property:boolean isPaused]
		
		Indicates whether the animation is paused. This shouldn't be adapted by user code.
		
		[property:boolean loop]
		
		Set to make the animation restart when the animation ends.
		
		[property:number interpolationType]
		
		The type to indicate how to interpolate between 2 data points.
		
		Methods
		[method:null play]([page:Number startTime])
		
		Starts the animation at the startTime (in seconds) of the animation.
		
		[method:null stop]()
		
		Stops the animation.
		
		[method:Boolean update]([page:Number deltaTimeMS])
		
		deltaTimeMS -- The time of the between the previous frame and this frame in miliseconds.
		
		
		Updates the animation in time. This shouldn't be called by user code. The animationHandler calls this method.
		
		[method:array interpolateCatmullRom]([page:Array points], [page:Number scale])
		
		points -- The 4 control point to calculate CatMullRom 
		scale -- The scale between the previous key and the nex key
		
		
		Interpolates the point based on the key. Is used in update.
		
		[method:Object getNextKeyWith]([page:String type], [page:Object h], [page:Number key])
		
		type -- The animationtype for the key. Can be "pos", "rot" and "scl".
		h -- The object of the hierarchy that catins the key 
		key -- The index of the next possible key.
		
		
		Gets the next key. Is used in Update.
		
		[method:Object getPrevKeyWith]([page:String type], [page:Object h], [page:Number key])
		
		type -- The animationtype for the key. Can be "pos", "rot" and "scl".
		h -- The object of the hierarchy that contains the key. 
		key -- The index of the prev possible key.
		
		
		Gets the previous key. Is used in Update.
