* This application shows a simple technique to animate and overlay two fragments
* on top of each other in order to provide a more immersive experience,
* as opposed to only having full screen transitions. When additional content

* the currently visible content can be moved into the background instead of
* being removed from the screen entirely. This effect can therefore
* provide a more natural way of displaying additional information to the user
* using a different fragment.
*
* In this specific demo, tapping on the screen toggles between the two
* animated states of the fragment. When the animation is called,
* the fragment with an image animates into the background while the fragment
* containing text slides up on top of it. When the animation is toggled once
* more, the text fragment slides back down and the image fragment regains
