Three Dollar Quill

• Wednesday: I looked over how the attrs plugin handles the evolve function.
• Thursday: I put together a weird implementation for saltate.
• Friday: I upgraded Mypy, and had trouble distringuishing between Tuple and tuple in the failure messages.
• Saturday: As I spun up the plugin development, I realized that I'm going to want to pull this out into a separate package as soon as I can.
• Sunday: I started writing tests, and using their failure details to refine the plugin design.
• Monday: I got the broad details of the plugin pretty much locked in, so it's in a good shape now.

Next week, I'm going to try to fully polish the plugin, as well as develop the generic motrfile enough to pull the plugins out into their own packages.
