Eventually we might want to put a Cargo workspace in this repository

I have a very basic pre-alpha Qstroke in the works with Simon's library, which is making me think: with Qstroke, Qmetadata, and Qglif, it's getting to be a lot of modules, and this will only increase.

I'm going to want to perhaps make this toplevel repo a Cargo workspace with Git submodules for every MFEQ module and a quick instruction about recursive Git submodule initialization.
