Description

This class implements a proctor that, upon destruction and unless its release method has previously been invoked, sets a deque endpoint (i.e., "start" or "finish" iterator) to a position within the deque. Both the endpoint and position are supplied at construction. See emplaceAndMoveToBack and emplaceAndMoveToFront for use cases.
