During the pre-setup phase, set the <A HREF="../DM/DM.html#DM">DM</A> that defines the base mesh of a DMForest forest. The forest will be hierarchically refined from the base, and all refinements/coarsenings of the forest will share its base. In general, two forest must share a bse to be comparable, to do things like construct interpolators.
