[Dune] Capability hasLeafIterator?

[Olaf Ippisch]

Dear Dune-Developers,

> The namespace Capabilities contains a traits class hasLeafIterator.
> I thought every grid implementation absolutely has to have leaf iterators?
I also think that hasLeafIterator is not necessary, as a leaf iterator is 
essential for the usability of a grid. However, I would suggest to introduce 
a capability hasLevelIterator as a level iterator is as far as I know only 
necessary for geometric multigrid. A grid without level iterator might 
therefore still make sense.

Regards,
Olaf
