[Dune] Periodic boundary conditions in YaspGrid

[Christian May]

Thanks for your answer, here is a tar file with an (almost) minimal source 
file and the result I get on my machine.
It creates a 2-dimensional grid with 3x3 elements. To my understanding, 
e.g. node 0 should have the same global number as node 3 and node 4 should 
have the same global node number as node 7, which it doesn't.

Thanks
Christian
