Simplex Category
Description
This PR reworks the simplex category to make it more amenable to defining diagrams. It also proves a whole host of properties about it, which required the introduction of antiinjective and antisurjective functions. I was not able to find a better name for these, so suggestions are welcome!
Finally, this PR also introduces a bit of machinery for constructing concrete categories: a macro is used to introduce top-level copattern matches so that we can get better goal display.
