[RZTransitionsManager setInteractionController:...] doesn't return what it promised #27
Description
The header doc for [RZTransitionsManager setInteractionController: fromViewController:toViewController:forAction:] claims it'll return a unique key to reference the pairing, but...
- due to a shadowed variable bug, it always returns
nil - the way it's currently written, there is no 'unique key' to return. It adds as many objects to the map as there are bits set in the action.
