Looks good overall and tests appear to pass. Worth considering how we structure the return of the functions, since using exception handling rather than conditionals is a design choice. One function appears to be duplicated. Otherwise good to go!

Thanks for the review, @tlarock! Someone pointed out a minor error in my simpliciality paper, so I'm determining what to do with that first before making your suggested changes.

Hi @tlarock --- I believe I addressed all of your comments. The URL checker fails, but this was addressed in another PR so it will go away once we merge into the main branch.

[tlarock]

Very close! Sorry to be a pain about the documentation, but hopefully easier to clairfy now than later :) Of course feel free to take or leave

[nwlandry]

@tlarock --- I believe I addressed your comments! I added more extensive documentation in the Notes section of the docstrings. Lmk what you think!

[tlarock]

Looks great @nwlandry! Ready for merging on my end.
