[Dune] [Dune-Commit] dune-grid r4163 - trunk/grid/common

It is like this. (*this) is a reference to IntersectionIterator< ... >. Then, 
*(*this) is a reference to the Intersection< ... >. Then, on the intersection, 
the boundary method calls the implementation (at least, this is the way I 
understand it).

Cheers,

Martin
