Tween<T extends dynamic> class

A linear interpolation between a begin and end value.

The lerp method defines how values of type T are interpolated. Subclasses override lerp for specific types (int, double, Color, etc.).

A Tween is an Animatable that maps a double in 0.0, 1.0 to a value of type T.
