Formatting Improvements

My apologies in advance for the two massive commits. This pull request mainly tackles code formatting. I noticed that there wasn’t much consistency in coding styles throughout (spaces between operators or not, etc.), so I made some changes to unify the coding style. Nearly all (if not all) of the operators now have one space before and after. Every comma now does not have a space before it and has one space after. This adheres to coding standards for readability.

Other than the commit for converting single character Strings to Chars, there should be zero code additions; only formatting changes.
