FFC compatibility issue
while working on some new forms I ran into a compatibility issue between HyTeG and a newer FEniCS version.
I had generated the forms with FFC version 2019.2.0.dev0. Apparently there have been changes w.r.t. the inheritance structure of the resulting classes when going from 2019.1.0.post0 to 2019.2.0.dev0 and as a result the new forms failed to compile in HyTeG.
I have not looked into that deeper, so I cannot say, if merely exchanging the header
src/hyteg/fenics/ufc.h would suffice, or whether deeper changes are involved. For the moment, just be aware, that you cannot use newer FFC versions.
