Create lifecycle

Disclaimer

We are moving to stabilize the Fiber, we need to start creating the lifecycle, I think in order to have a better adoption, we can follow the React line or we can change it if everyone agrees.

For the purpose of this library, we have to pick up and evolve our lifecycle for animations.

Please leave your thoughts.
