`O_o`
So that when you create a hasse diagram, and later plot it, it remembers
to plot it going up. But I can live without this feature.

and only do something different if some guy calls
`my_poset.show(mess_up_top_and_bottom=True)` ?
That is not the question. The goal is to always plot the poset with top on
top.
But to plot a poset we need to plot a digraph. So either it's ok if the
acyclic layout of graphs always points up. Or we need to have an option
(of the graph, or just of Graph.plot) to specify whether the acyclic
layout goes up or down.
