Add example for tick()

[AngeloMateus]

Could you add an example for calling tick()?

I have no idea what Targetable needs: tween.tick(Duration::ZERO, ???, e, &mut writer);

Yes we could add that. Although really Tweenable::tick() is not really designed to be used manually by default; instead the component_animator_system() will call it automatically. You can have a look at its implementation to understand how tick() should be called:
