[name]
		Runs a keyframe animation as imported from the [page:ColladaLoader].
		Examples
		[example:webgl_loader_collada_keyframe loader / collada / keyframe ]
		Constructor
		[name]([page:Object data])
		
		data -- An individual animation object from a the [page:ColladaLoader], e.g. loadedColladaObj.animations[0] 
		
		
		Creates a new keyframe animation and initializes it to the first keyframes.
		
		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.
		
		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:null update]([page:Float deltaTime])
		
		deltaTime -- The change in time in seconds
		
		
		Updates the keyframe animation
		
		[method:Object getNextKeyWith]([page:String sid], [page:Integer h], [page:Integer key])
		
		sid -- The string id 
		h -- The index in the heirarchy to use
		key -- The index of which key to start from
		
		
		Used internally to traverse the animation
		
		[method:Object getPrevKeyWith]([page:String sid], [page:Integer h], [page:Integer key])
		
		sid -- The string id 
		h -- The index in the heirarchy to use
		key -- The index of which key to start from
		
		
		Used internally to traverse the animation
