[Dune] Periodic boundary conditions in YaspGrid

[Christian May]

Hello together,

in the YaspGrid constructor, directions can be labeled as periodic. 
However, I don't see a difference in the result. Shouldn't vertices at 
opposite faces in that direction just be assigned the same global node 
number? Apparently, that doesn't happen, so how do you find out which node 
is a neighbor then?

Thanks a lot in advance
Christian
