Subject: [PATCH] OK, now we run 'routing' for the nox configurations with
loops.
Unfortunately, I can't test this at the moment since nox seems not to
be able to find the routing module.
Added/renamed examples: grid.py, tree1024.py
Added -v flag to nox arguments, so we have some chance of figuring
out why nox is dying, as it generally is.
