A MDDCollIter represents an iterator for a persistent MDD collection.
If a collection is changed (elements are removed or added to/from the
collection) between creation of an iterator for it and the execution of
other operations on the iterator, the behavior of the istent Iterator
is undefined.
The {\tt MDDColl::createIterator()} for the object to be scanned should
be used to create a new iterator object.
