 * <p>
 * Internally Mosby will hold some relays to ensure that no items emitted from the ViewState
 * Observable will be lost while viewState is not attached nor that the subscriptions to
 * viewState
 * intents will cause memory leaks while viewState detached.
 * </p>
 *
 * Typically this method is used in {@link #bindIntents()}  like this:

 *   Observable<MyViewState> viewState =  ... ;
 *   subscribeViewStateConsumerActually(viewState, new ViewStateConsumer() {
 *      @Override
 *      public void accept(MyView view, MyViewState viewState){

 *
 * @param viewStateObservable The Observable emitting new ViewState. Typically an intent {@link
 * #intent(ViewIntentBinder)} causes the underlying business logic to do a change and eventually
 * create a new ViewState.
 * @param consumer {@link ViewStateConsumer} The consumer that will update ("render") the view.
