Hi All,

I also support that we need some extensions of the interface, like
LeafIterators for all codims and partitionType. However, I also agree
with Robert, that we should be careful with extensions. We should make a
detailed list with all requests, discuss aspects of these changes by
email and then decide on our meeting on July 9.

Who wants to compile the list ?
