# Class AnimationManager

java.lang.Object

public final class AnimationManager extends Object
Animation manager concentrates all of the animations for a given form into a single place that allows us to manage all mutations to a Form in a way the prevents collisions between mutations. The one type of animation that isn't handled by this class is the form level transition, replace transitions are handled by this class.
