[Dune] DGFParser interface

[Robert Kloefkorn]

Hi all,

i would suggest to handle this problem like this:

The class GridPtr<GridType> is derived from GridType and the
specialisations call the right constructor and they already do in the
specialised generate method. Then GridPtr<GridType> is of the type
GridType and can be treated as GridType.

This in an easy way to add a constructor common for all grids, taking
the DGF file.

Regards,

R
