Modified TableViewController to refresh to demonstrate issue with drawerView appearing
Fixed issue with scrolling to refresh causing drawer view to show on cell. If the pan UIGestureRecognizer cancels and deltaPan == 0, we remove the drawer and shadow views from superview. They will be reinstalled the next time the gesture recognizer pan begins.
