[Dune] How to iterate over the vertices of an element?

[Oliver Sander]

Hi Arne!
If you want the actual entity there is a method (of the Entity)

template<int cc> Codim< cc >::EntityPointer 
<cid:part1.04030004.06040204 at mi.fu-berlin.de> entity 
<cid:part2.09090906.02090403 at mi.fu-berlin.de> (int i) const  Access to 
subentity |i| of codimension |cc|.

If you just want the vertex entity to get its id or index I suggest you 
use the
subIndex methods of the index and id sets.  These can be expected to be 
a lot faster.

enjoy,
Oliver
