> Thanks for your help on the code. I'm glad you were able to get things
working with the sage parent/element/etc framework. I wasn't quite sure
how to do that.
Not a problem. I hope a lot of the design is clear and makes sense.
There's still a general question of what to do with subsets (here
geodesics) of a given set (the entire plane) in terms of parents (so we
can induce coercions on the subsets [geodesics]), but that is a separate,
quite large, and probably thorny issue that we can't solve here.

but which haven't been merged into this branch yet. I'll hopefully have
time to commit a patch that fixes the remaining bugs that I know about in
the next week or two.
Let me know as things get merged in and I can review those changes so we
can get this included into Sage.
FYI, a typo got introduced in `c612e31`:
