Pitch: Abstract Algebra (linked to tiny SPM package)

Hey! Very excited about this package (as you might have seen from my three PRs #33 #34 #36 )!

Earlier this summer/fall I started playing around with Abstract Algebra in Swift, I repackage it as a SPM package this hour, just to be able to show it to you fellow math lovers. I just called it [AbstractAlgebra](https://github.com/Sajjon/AbstractAlgebra) - for lack of imagination. It is quite crude and probably ridiculously slow but shows some ideas.

In general, what fits into this package? I fully understand if e.g. Abstract algebra does not fit...

Thanks!

Review the linked AbstractAlgebra Swift package and the swift-numerics project scope first. The issue does not name a file, test, entry point, or concrete acceptance condition, so a contributor would need maintainer direction before defining what done means.
