[Dune] Parallel CG Solver

[Arne Rekdal]

I am using this constructor already.

The file is attached (it depends on dune-grid, dune-istl, and  
dune-disc). Now it uses the UniversalGlobalMapper, and prints the  
output as in the previous post. If I instead change it to use the  
grid.globalIdSet().id it produces MPI errors.


Thanks!
