A Container is an object used to store other objects and taking care of the

management of the memory used by the objects it contains.

A ReversibleContainer is a Container that has iterators that meet the
|
||||
requirements of either BidirectionalIterator or RandomAccessIterator. Such
|

iterators allow a ReversibleContainer to be iterated over in reverse.
