A sparse array of managed objects.
This might be used as a simple array class for reference counted objects. This class assumes that objects in the array exist when assigned, and that gaps in the array are positions that do not reference any object. Objects are automatically created (create on access/modify when an array position is referenced for the first time. This is an abstract class because it is a type factory for objects who's derived class form constructor is not known in advance and is a helper class for the sarray template.
