This function doesn't give you an iterator or circulator
that you can advance. Instead YOU have to give it an
'output iterator'. This is an iterator in that the function
can write the result to. For example this can be:

std::list cells;

tds.incident_cells(.., std::back_inserter(cells));

The function back_inserter creates an output iterator
and after the call you just traverse the list to do
something with the cells.

don't hesitate to tell me if this explanation wasn't
clear enough.

best regards,

andreas
