        Standard diff of two sets.

        Parameters:
        left        An iterable
        right       An iterable

        Return:
        tuple       (added, removed, matched)

        added       Set of items in right but not left
        removed     Set of items in left but not right
        matched     Set of items in both left and right.  This is
                    in the form of tuples with the matching item
                    from left and right
