[Dune] Iterator for all edges of a face?

[Dragan Vidovic]

Hi Oliver

I tried that first. Here is what grid-howto says:

IntersectionIterator provides access to all entities of codimension 0
that have an intersection of codimension
1 with a given entity of codimension 0.

And the compiler says the same thing - it does not work for, let's
say, codimension 1 (triangle) having an intersection of codimension
2 (edge) with another triangle, all in a 3d mesh.

Cheers,

Dragan
