React
A ReactHost is an object that manages a single ReactInstance. A ReactHost can be constructed without initializing the ReactInstance, and it will continue to exist after the instance is destroyed.
The implementation of this interface should be Thread Safe

Functions
Add a listener to be notified of ReactInstance events.
To be called to create and setup an ReactSurface.

To be called when back button is pressed
To be called when the host activity is destroyed.
To be called when the host activity is about to go into the background as the result of user choice.
To be called when the host activity is paused.

This function can be used to initialize the ReactInstance in a background thread before a surface needs to be rendered. It is not necessary to call this function; startSurface() will initialize the ReactInstance if it hasn't been preloaded.
