Hack Week Day 2

I was supposed to write a TUI for GraphBook today. I wasn't really successful; I was trying to learn curses and figure out how that works. I was also more distracted today, which I need to double down on tomorrow.

I did get a sort of proto-interface using the Python curses library, but I think urwid will be a better option going forward and I'm going to try to get something together with that.
