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.

In order to have a well documented API we need to describe what each class, struct, enum and method responsibilities are and how to use it.

Currently, the framework is lagging unit testing. Add some unit test.

OutMode actually is specified once for all edges like this:

outMode: OutMode.out

But I think that more customizable options can bring more cool effects, gravity can benefit this setup.

The options should become something like this:

outMode: {
    top: OutMode.none,
    /*left: OutMode.bounce,
    right: OutMode.bounce,
    bottom: OutMode.bounce,*
