What I want here is a Cartesian topology that allows arbitrary dof layout. DMCartesian almost does this in any dimension, but cannot do edges and faces correctly since I could not figure out the gray code for this. Note, that this is not trivial with DMDA, because 1) The communication code would have to be fixed 2) It is not easy (ugly) to construct an FEM iteration 3) It also does nto know about edges and faces > Also since Mesh is a generic word but DMMesh is built on Sieve should > DMMesh be renamed to DMSieve? I don't like that, because no one will understand what we are talking about. DMMesh makes sense. I might be alright with DMUnstructuredMesh, but that is overkill.
