Description

PR #392 should have the batteries for DG - but just for scalar problems. If we have vector valued problems, then our flux space becomes matrix-valued (think about displacement and stress). For convenience we could provide some handlers for handling matrix valued problems. This way DG can be implemented in a cleaner way than reformulating everything in Voigt notation beforehand.
