Comment (by dcoudert):
This is not so clear. Here we have an iterator. We will typically use it
like
{{{
for e in G.random_edge_iterator():
do something
if <some condition>:
break
}}}
In such case, you expect the loop to do nothing if the graph has no edge,
as will be the case using `G.edge_iterator()`. Raising an error is not
necessarily what we want.
The last commit raise a stopiteration. Is it ok?
