[Dune] Grid format for unstructured grids from GMSH files

[Andreas Dedner]

Hi,

I can think of two possible reasons:
1) something went wrong during configuration and Alberta was not found.
    Have a look at dune-grid/config.log and search for SUMMARY there it
    should say if alberta was found.
2) You forgot to include <dune/grid/albertagrid.hh>

Best
Andreas
