modified to set the stackController property earlier.
Added methods to help using UIGestureRecognizer's requireGestureRecognizerToFail:
removed wrapping methods that caused a crash
I have changed one piece of code that now sets the frames of the rootviewcontroller and floatingviewcontroller to that of the stackedviewcontroller's bounds instead of using hard coded values.
