It's never been publically released, due to lack of docs.  But it's pretty
well commented.  It started out as an isosurface update to the mur.inc, but
then I decided that the algorithm used in mur.inc was inadequate for my
needs.  If you want a copy, let me know and I'll send you the files.

They're not as hard as they seem to be at first glance.  I've become quite
enamored with them.  But there is a learning curve, mostly due to a lot of
parameters that, without a good idea of how they work, don't make much
sense.
