Summary:fast & accurate implementation
See https://github.com/gre/bezier-easing
the library is embedded in React Native
fixes#6207 & to follow #6340 (or to replace it)

tests
---
[the lib tests](https://github.com/gre/bezier-easing/blob/master/test/test.js) ensure the library is accurate.
It is tested that the library have a precision better than ±0.000001 .
performance
---
On my macbook pro, [the lib benchmark](https://github.com/gre/bezier-easing/blob/master/benchmark.js) have:
```
BezierEasing: instanciation x 1,043,725 ops/sec ±1.46% (82 runs sampled)
BezierEasing: call x 7,866,642 ops/sec ±0.93% (85 runs sampled)
BezierEasing: instanciation + call x 803,051 ops/sec ±1.58% (74 runs sampled)
```

Summary: @public
This diff does a couple of things:
- Move all the code in a src/ folder
- Move bezier.js in the Animated folder
- Rename Animated.js into AnimatedImplementation.js and adds two entry points: AnimatedReactNative.js and AnimatedWeb.js
- Implement very dumb polyfills for flattenStyle, Set and InteractionManager
- Import my work in progress demo.html file to make sure that the code is actually working.
Everything is not working correctly:
- It calls forceUpdate on every frame and doesn't use bindings because setNativeProps is not implemented
- None of the style: {transform} are working because React web doesn't know about the array notation for transform
- The demo need more work
