Joshua Gross 3331962279 C++ Fabric Core LayoutAnimations
Summary:
This is the V1 implementation of Fabric Core LayoutAnimations.

The intention is to structure this in such a way that it's easy for each platform to customize the "AnimationDriver" class (to do platform-specific optimizations) without changing the KeyFrameManager at all.

In the future, this structure and architecture should allow us to iterate faster on new animation APIs.
