Author(s):	hdaniels

	to store the name-value pairs. Instead, use another ICollection
	class such as OE.Core.Collections.Set.
	No empty constructor, specialized for IMap
	- Changes to the map are reflected here, and vice-versa.
	- Supports removal and removes the corresponding map entry from the map
	(Iterator.remove, Collection.remove, removeAll, retainAll and clear) .
	- Do not support add and addAll.
