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.
