Barry, INSERT_VALUES is currently hard-coded.  When we talked at the lab,
you seemed rather down on using DMComposite, but I don't see a good
alternative for e.g. equations in a volume coupled to equations on the
surface.  In any case, should DMCompositeGather() take an InsertMode
argument?  Or is there a different way you had in mind?
