This object should handle constraining degrees of freedom and function spaces on a subdomain of the mesh. Eventually it will be a full-fledged PETSc DM object. For problems with mixed discretization, there will be a dMFS (multi function space) object. All fields in a dMFS will need to be discretized over a dFS and that dFS must share the same dQuotient. If this property is not satisfied, just use Barry's DMComposite. Signed-off-by: Jed Brown <jed@59A2.org>
