I looked at CUE and lattices and I realize CUE fits right in with some other work I'm doing!

For now I made it possible to draw Hasse diagrams. That seemed like a fun way to extend the project. I did not add any CUE examples, that seemed out of scope but who knows, there could be some applied examples in the future.

I see that lattices are commonly drawn with straight line, but that is mostly historical (how it was done). I decided to allow bezier edges as well because, why not?
