Fix typos, grammar, comment clarification and standardization.

[Epsiloong]

Description

I decided to fix any typos, grammar issues, or unclear comments as well as standardize the format of the comments while reading through the repo to gain a better understanding of how everything works. Nearly all changes are to comments only, however, there is one variable name that was renamed due to a typo.

All comments now start with a capital and any multi-line comments have better punctuation to be more easily read. This brings the comments format closer to what the rust foundation recommends and improves the overall readability. I tried to keep the content of each comment as close to the original as I could, however, there were a few comments that were very difficult to read and those were heavily changed.
