Description
For the entity iterator it was decided to be compatible with the std::forward_iterator.
It would be nice to have the same for the IntersectionIterator.
I attached two patches which does introduce this functionality.
The first one specializes the iterator traits for the IntersectionIterator.
With this patch counting the number of intersections can be done within this one line:
std::difference( gv.ibegin(entity), gv.iend( entity ) ) The second one introduces the post-increment operator and the default constructor.
