Good stuff, thanks. Few questions and suggestions below.

Apologies in advance if some comments are outdated -- looks like some updates came in as I was finishing up my review.

Checking in Delaunay triangulation

Sorry, can you revert this commit and put it in a separate PR? If you're comfortable with git rebase, you can chain the PR branches on top of each other, then rebase the newer PRs on top of the main branch as the older PRs get merged.

I concede that that's a lot more burdensome on you when the PRs have dependencies on each other, but it makes my life as a reviewer a lot easier. I can get through a bunch of smaller PRs much more efficiently than one big PR.

No worries if reverting the commit is a problem this time, but going forward let's try to figure out a workflow that involves chaining multiple smaller PRs, since that's the only way that I'll realistically be able to continue reviewing them.

Ignore the Delaunay files for now. Moving forward, I will daisy chain the PRs. The next PR will be Delaunay related and we can discuss that in more detail then.

Big fan of the updated docstrings. It's a lot more clear what's going on now, thanks.

Just a heads up -- if I add more than like 10 review comments at once, GitHub collapses some of the comments and you need to click on [Load more...] to reveal them. You might not have seen some of my earlier comments because of this.

Moving forward, I will daisy chain the PRs.

Thanks! I really appreciate it.

LGTM, thanks for addressing all of my questions and comments
