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).

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.
