This class implements the basic functionality of Animations for Wonderlands. All animations pass through 4 specific stages:

Waiting - this is the state animations are in when they are just started, before they run their prologue (perform any tasks they need to do before the animation actually starts)

Running - this is the state animations are in when they are actually running

Stopped - this is the state animations are in after they stop running but before they execute their prologue

Finished - this is the state animations are in after they finish their epilogue (perform any tasks they need to do after the animation completes).

	getAnimatedObject Return the object that this animation affects
	getLoopCount Returns the animation's current loop count
	getState Returns the current state of the animation.
	isDone Returns true if the animation is running
	isLooping Returns true if the animation is looping
	setLoopCount: Sets the animation's current loop count
	setUndoable: Sets the animation's undoable property

	copy Answer another instance just like the receiver. Subclasses typically override this method; they typically do not override shallowCopy.
	epilogue: This method does any work that needs to be done after an interation of the animation finishes.
	getDuration This method returns the duration of the animation.
	loop This method causes an animation to loop forever.
	loop: This method causes an animation to loop for the specified number of times.
	looped This method creates a copy of an animation and loops it forever.
	looped: This method creates a copy of an animation and loops it for the specified number of times.
	pause This method pauses an active Animation.
	prologue: This method does any work that needs to be done before the animation starts, including possibly adding the current state to the undo stack.
	resume This method resumes a paused animation
	start This method starts an existing animation
	stop This method changes the state of an animation to stopped. If it is currently active, the Scheduler will remove it from the list of active animations.
	stopLooping This method causes the animation to stop looping; the current interation of the animation completes before the animation stops.
	update: Updates the animation using the current Wonderland time

	private	top
	scaleDuration: Scales the animation's duration by the specified amount
	setDirection: Sets the animation's direction variable

	reversing	top
	reverseDirection Changes the direction an animation runs in (forward or in reverse)
