TickerComponent mixin
Mixin for ControlModel to pass TickerProvider from CoreWidget - ControlWidget or ControllableWidget. Enables to construct AnimationController and control animations.
Typically used as private ControlModel next to Widget class. This solution helps to separate animation/UI logic, actual business logic and pure UI.
Also Widget must use TickerControl or SingleTickerControl to enable vsync provider or pass TickerProvider from other place by calling provideTicker.
