The problem is that I basically am creating a model in which I have an egg crate
pattern interface between two different liquids.  I used isosurface to create
the two different regions.  Just putting them on top of each other (or close to
eachother) does not work properly (I see the interface even if I make the two
regions have the same ior).  I actually have scratched my head a while trying
to make the interface "disappear" when the two regions have the same ior as it
should.  I noticed that if I overlap by a very little amount it seems to work
perfectly.  Actually, if it randomly chose a ior it might be fine since it is
such a tiny region.  I would just like to know what it is doing.  Maybe it
chooses which ever is listed first or something, depends on how the merge
routine is written I guess?
