Summary:
`flattenOffset` has proven extremely useful, especially when dealing with pan responders and other gesture based animations, but I've also found a number of use cases for the inverse. This diff introduces `extractOffset`, which sets the offset value to the base value, and resets the base value to zero. A common use case would be to extractOffset onGrant and flattenOffset onRelease.

Summary:
This diff implements NativeAnimation offsets on Android. Running the examples should show no change; however, calling `setOffset()` should offset the final value for any value node by that amount. This brings Android up to date with JS and iOS animation APIs.

Summary:
Adds support for `Animated.Value#addListener` for native driven nodes on Android. This is based on work by skevy in the exponent RN fork. Also adds a UIExplorer example.
** Test plan **
Run unit tests
Tested that by adding a listener to a native driven animated node and checked that the listener callback is called properly.
Also tested that it doesn't crash on iOS that doesn't support this yet.

Summary:This change adds suport native animated support for Animated.add.
Animated.add lets you declare node that outputs a sum of it input nodes.
**Test Plan**
Play with the following playground app: https://gist.github.com/39de37faf07480fcd7d1
Run JS tests: `npm test Libraries/Animated/src/__tests__/AnimatedNative-test.js`
Run java tests: `buck test ReactAndroid/src/test/java/com/facebook/react/animated`

Summary:This is the first from the series of PRs I'm going to be sending shorty that would let Animated.js animations to run off the JS thread (for Android only).
This PR introduce a new native module that will be used for offloading animations - NativeAnimatedModule. It has a simple API that allows for animated nodes management via methods like: create/drop animated node, connect/disconnect nodes, start animation of a value node, attach/detach animated from a native view.
Similarly to how we handle UIManager view hierarchy updates we create a queue of animated graph operations that are then executed on the UI thread. This isolates us from problems that may be caused by concurrent updates of animated graph while UI thread is "executing" the animation.
The most important class NativeAnimatedNodesManager.java implements a management interface for animated nodes graph as well as implements a graph traversal algorithm that is run for each animation frame. For each animation frame we visit animated nodes th
