StatefulBuilder class

A platonic component that both has state and calls a closure to obtain its child component.

The StateSetter function passed to the builder is used to invoke a rebuild instead of a typical State's State.setState.

Since the builder is re-invoked when the StateSetter is called, any variables that represents state should be kept outside the builder function.
