Testing the possibility of using UIDynamicAnimator as a cross framework Physics Engine
This is a test to prove a concept:
The UIDynamicAnimator does not care what its animating, as long as it responds to the UIDynamicItem protocol. I hypothesized that one could cause SpriteKit Nodes and UIView views to animate and collide in the UIDynamicAnimator.
I had to implement bounds, center and transform in SKNode to achieve this, and the project currently works (kind of)
TODO: Flip coordinate plane in SpriteKit so that it looks correct.
Implement transform for SKNode (I am not sure on the math for this yet)
I will gladly except pull requests to implement these features.
