Comment:
The updated patch fixes the issue with cones and fans by adding a ``key``
argument to FinitePoset. Using it, equal but not identical Cone's and
Fan's create distinct posets.
I also folded in Christian's order_complex fix.
To me the whole thing seems ready to go.
Sorry, I screwed up and refreshed my changes directly in the main patch.
So I have attached a diff between the previous and new version. It's not
super-readable, but it should point to those few places that need review.
