[dune-pdelab] [dune-functions] [dune-pdelab-commit] [branch] dune-pdelab - 'feature/new-functions-interface' updated

Hi Christian,

I wanted to give this a try and compiled one of the pdelab test programs
from the book (without changing anything, hoping that your changes are
backward compatible).  I get the following compiler output.  Any idea?

Best,
Oliver
