Add Documentation to code
As a developer, I want to have documentation for various aspects of code in order for new developers to get around the code easily.
The most important parts to document are various features beyond the basics of UIKit development. For example, we don't need to document what a UITableViewCell file is, but we should document things we changed and why we did them.
In order to best document code, we should use Xcode's markup formatting. This can be read by Jazzy to generate docs. https://developer.apple.com/library/content/documentation/Xcode/Reference/xcode_markup_formatting_ref/
