[Dune] Suppressing output from .dgf parser

[Dedner, Andreas]

Hi.
The problem is a different one:
>From the output it seems that Eike is using AluGrid<2,3>. i.e., 
the 2d alugrid version and that does not run in parallel. 
So you are simply getting 1000+ processes running the same problem and all 
having rank=0.
Best
Andreas

Hi Eike,

Do you want to run 1000 sequential simulations, or do you want to run one
simulation on 1000 cores? If the latter, please check that the summary says
that ALUGrid is compiled for parallel usage, i.e. that the corrosponding
summary line reads:

ALUGrid.................: version 1.50 (parallel)

(In my simulations, the message is only printed once even for parallel runs,
so you probably did not compile the ALU library for parallel usage...)

cheers
  Andreas
