Yes sure. I am in correspondence with him and I am waiting for his reply
right now. So before I flood him with this new email I'd like to wait for
his answer.
In the meantime I'd like to push this thing further without having to wait
for his fix/reply.
One way we could try is to call Digraph::set_heuristic or something.
Though I was not able to make it work in cython due to some enum typedefs
issue.
So what do you suggest that we do? Just avoid digraphs for now?

think that in C his algorithm would be slower than yours, but not in
Python `;-)`
We can leave the code as is then!
As far as I get the current state of affairs, we need to
1. Leave out the is_isomorphic thing
2. Find a workaround for the digraph thing.
and then we are almost done?
Best,
Jernej
