Build better examples

The current example app is a really simple approach on what can be done with ViewAnimator. Even though the library is not complex to integrate and use on your own projects it would be nice to show how to use different animations in different scenarios.

I'd be replicating the app should on the animations Complex header.

Added the good first issue label, I'd really appreciate anyone who wants to send a PR with a simple implementation (it doesn't have to be the example above). Any use case that you feel ViewAnimator animations look good 😄
