OK. We can add an include statement in dgfparser/gridtype.hh and a

The point is, that the functionality is a different one. dgfgrid.hh
should include all implementations and not gridtype.hh. There are
different reasons:

1) if using dgf without gridtype, you have to include all header
2) gridtype.hh has nothing to do with dgf and can be used without
   it. Why shouldn't we add the dgf includes to quadrature.hh?
   Wouldn't that be as convinient as including them in
   gridtype.hh. The only duty for gridtype.hh is to construct the

And what about the foo-format? Then we should also include
foo-sgrid.hh and foo-alberta.h in gridtype.hh!
