style: convert variables to lowercase

[john-halloran]

This is a mostly complete conversion of variables to lowercase. Have tested to make sure behavior remains the same with before renaming. I'm still working on a few minor variables. The cleanup of old files is no longer included in this PR.

this is sooo much better. Please see my comments. Mostly on the docstrings, which are way more easily understood now.

When these things are fixed I am inclined to merge this, but we probably should revisit it. In general, we would prefer to write tests before we do the decsign and the functions, but this may not be a good strategy here. @john-halloran what are your thoughts on this.

I think for understandability, it will be good to get this renaming out of the way asap, but otherwise I agree with all of this. Tests will be the next thing I work on and that will happen before any further development on the algorithms, to avoid our results drifting from the known-working state they are in currently.

Everything should be renamed now, so if you see anything still capitalized, flag that in your review. Feel free to merge once all your feedback is addressed. Thanks for the help so far!

really good. Just one or two things and I can merge

[john-halloran]

Okay, that stuff should be in. Let me know if I had the right idea.

@john-halloran nailed it! nicely done. Code is 1000% more readable!
