Comment (by chapoton):
Hello Nathann,
I have now made good use of the `is_tree` function.
Would you prefer if I put my auxiliary function inside the new method ? I
do not see how to avoid it completely. I need to choose an arbitray
orientation of the graph, and for this I am using the way the edges are
given by a pair (i,j). Then I need to know how every cycle is oriented,
some arrows being in the wrong direction.
Is this really necessary to smash all my commits (not patches) into one ?
I would prefer not to.
