Get the base DM 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 base to be comparable, to do things like construct interpolators.
PetscErrorCode DMForestGetBaseDM(DM dm, DM *base)
dm -the forest
base -the base DM of the forest
After DMSetUp(), the base DM will be redundantly distributed across MPI processes
