ImplicitlyAnimatedWidget class

An abstract widget for building widgets that gradually change their values over a period of time.

Subclasses' States must provide a way to visit the subclass's relevant fields to animate. ImplicitlyAnimatedWidget will then automatically interpolate and animate those fields using the provided duration and curve when those fields change.
