Add a "hasEmptyIntersection" method to ImmutablePointerSet. We do this by doing a traversal of our sorted lists in a similar manner as one would when one is merging two such sets, i.e. one has two iterators and always advances the iterator that has a value that is less than the other. If we ever hit a situation where the two iterators equal, we must have a non-empty intersection. A unittest that exercises very basic functionality is provided as well.
