AnimationWithParentMixin<T> mixin Null safety

Implements most of the Animation interface by deferring its behavior to a given parent Animation.

To implement an Animation that is driven by a parent, it is only necessary to mix in this class, implement parent, and implement T get value.

To define a mapping from values in the range 0..1, consider subclassing Tween instead.
