Three Dollar Quill

Did the simplest possible layout that I'm comfortable with; the result is a little iffy currently, and I might rework it slightly later, but it's fine for now.

All of that cleanup got me comfortable writing more tests for the matrix module. Just a few more tests, and it should be covered, and I can start working on other modules.

For now, though, I'm just going to take things easy.

Good night.
