 // experiences. Establishes communication with the view manager.
 // A window manager wishing to use this core should create and own an instance
 // of this object. They may implement the associated ViewManager/WindowManager
 // delegate interfaces exposed by the view manager, this object provides the
 // canonical implementation of said interfaces but will call out to the wrapped
 // instances.
