Reactive React

This is a PoC for applying Reactive Programming with React functional component.

For the overview, we have a simple React component like this:

<App />
  |- <MouseTracker />

And a mouse event stream created with highland.js, it transform the mousemove event into a stream of mouse position.

In <App/> component, we subscribe to that stream, for every event, we update the <MouseTracker/> component with a new position data.
