Fixed an issue related to multiple panning cells but removing superview for drawerView and shadowView is problematic. Fixed gestureRecognizerShouldBegin to recognize self and drawerView. ADded delegate method for panningTableViewCell:shouldRecognizeGestureRecognizer:simultaneouslyWithGestureRecognizer:. Added delegate method for panningTableViewCell:shouldPanWithGestureRecognizer:. Added support method for checking if panning is in progress. Added setDrawerRevealed with completion block. Added gesture recognizer getters.
