[Dune-devel] Validity of GridView after grid changes

But this light weight might be that you just store the expensive data
outside the gridview, still it must be ensured somehow that the
hostgridview and the extra data are in sync. Otherwise you could still
work with the gridview, but it would produce oscure results.

Ciao Christian
