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.

Like themes, a responsive section is needed in options.

Something like:

{
    /* omissis, this is the main options object */
    responsive: [{
        maxWidth: 400,
        options: { /* omissis */ }
    }, {
        maxWidth: 800,
        options: { /* omissis */ }
    }]
}

If the width is greater than the bigger maxWidth the main settings will be used,

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