[Dune] Problem with GmshReader

[Martin Nolte]

Looks like you use some special purpose UG code, here. I don't even know why
ALU's constructor should be taking an integer constant. Maybe you should use
the following construction

GridType *grid = GmshReader< GridType >::read( filename );

Best,

Martin
