This class design violates the usual rules of good OO style: it has polymorphic behavior packed into a single class. The justification for this decision is to avoid the expense of the clone() operations that would be required by the copy ctor for iterators were a polymorphic class heirarchy used.
Two cell set types exist: explicit, where the member cells LIDs are enumerated in a physical Set<int> object, and implicit, where no physical Set is made, rather, the sequence of cell LIDs is obtained through some scheme of walking the mesh.
The only cell sets that can represented implicitly are the set of all cells of a given dimension.

CellIteratorPos is used to specify whether a new CellIterator is positioned at the beginning or end of a set.
