[Dune] Example on IteratorRange

[Christian Engwer]

Dear Aleksejs,

I'm sorry, but I don't uderstand your question. What exactly do you
miss in the documentation?

There are examples for all functions like elements(gv),
intersection(e), entities(gv, dim/codim)...

as shown in the examples you are not calling methods on a class. These
are free functions operating on a gridview, adding syntactic sugar
ontop of the begin/end methods of the gridview.
