mvrxViewId

Override this to supply a globally unique id for this MvRxView. If your MavericksView is being recreated due to a lifecycle event (e.g. rotation) you should assign a consistent id. Likely this means you should save the id in onSaveInstance state. The viewId will not be accessed until a subscribe method is called. Accessing mvrxViewId before calling super.onCreate() will cause a crash.
