Should the refinement level be copied over by DMCoarsen (and the coarsen
level be copied by DMRefine)?
It's useful for diagnostics to be able to define a universal level. If I
use PCMG and -snes_grid_sequence, there is effectively a sequence like
DMCreate(,dm0); // r=0,c=0
DMRefine(dm0,dmf); //
That sounds fine to me.

Now the next round:
For semi-coarsening, we used to have stuff like -da_refine_hierarchy_x
1,1,3 -da_refine_hierarchy_y 2,2,1 -da_refine_hierarchy_z 2,2,1. Two
changes make this harder now:
1. You essentially got rid of DMRefineHierarchy (it's not called any more),
so each call to DMRefine and

The associated ugly hackery is here. I'd welcome suggestions for a better
way to do this.
