Replying to [comment:182 ncohen]:
> The bad news is that if you wanted self-intersecting paths you will not
get them by calling `all_paths`, and the current code is wrong ?..
The current code (in the sense of: The code provided by the ticket branch)
creates a sub-class "Quiver" of `DiGraph`, and this sub-class overrides
the `all_paths` method. But now, the plan is to not have a sub-class,
since mathematically a quiver ''is'' a digraph (with multiple edges and
loops).
