If the cursor is not yet initialized, MovePrevUnique is identical to 
            MoveLast()()(). Otherwise, move the cursor to the previous
            non-duplicate key in the database, and store that key and associated
            datum in Current. MovePrevUnique will return false if
            no non-duplicate key/data pairs exist after the cursor position in
            the database.
