Comment:
This should fix the problems. I reverted the change that made
`hasse_diagram()`'s labels be the labels as opposed to (for non-facade
parents) elements of the poset. I also made a related change in `dual()`.
I uninstalled dot2tex from my machine and was able to reproduce the error
and checked things in that state and after re-installing dot2tex.
