Higher-level providers (or extensions) might want to register new synthetic top-level paths for doing special stuff. This is the way to do just that. Just be careful to complete all this before Start finishes, or before you start your own auto-spawned actors.

	string name,
	IInternalActorRef actor
)

member RegisterExtraName : 
        name : string * 
        actor : IInternalActorRef -> unit
