[Dune] YaspGrid Entities of higher codim.

Hi Peter,

I see, I see.

But I have to add that this argument would mean, that all grids 
supporting entities of higher codimension would be slow. And this is not 
the case. I think there are some shortcomings in the implementation that 
should be removed and SGrid would be at least a usable Grid. Also, an 
implementation of a structured grid that is much slower than all other 
unstructured grids is not really a good advertisement for a package like 
Dune. But of course somebody has to do it and like always we are short 
on man power I guess.

Cheers

Robert
