I am working on a problem in which I have 2 groups of clusters, each of
which was generated from the same original list of members.  Within each
group, the clusters cover the original list of members many times over.
What I am interested in finding is the number of common elements in every
pair of clusters when taking one from each group.  In short, I need a FAST
way of finding the number of common elements in two groups, as this process
will be over all pairs.  (The elements in the two groups can be numeric if
absolutely necessary, but it would be nice to be general here.)

Thanks,
Sean
