TreeBag with comparator does not store non-key duplicates.

When storing objects that are sorted by a Comparator, if the differences in the objects are not in the comparator the same version of the object is returned. I expected that the sorted bag would work like a DB table with a non-unique key – ordered but duplicate only determined by Object.equals().

I have implemented this type of bag using a TreeMap of List. My implementation uses the Jena ExtendedIterator to make building the iterator() and array() methods easier.

Will attach the code.
