Pamela's Merge Request: 09-09-2021

This merge request includes all of my additions and modifications to both 01-40 and the Application Examples. In the applications examples that have references, in the references section the reference to keep is the one right under the word "References". Where it says "remove this part", you can remove the text below that if you think the reference info on top looks good. For the purposes and descriptions, I added purposes and moved extra text into the descriptions section. Keane did a really good job with writing some text - I did not want to remove anything so I only changed the location of it (put into descriptions). Essentially I only took out repeated text, kept what the authors wrote, and just made everything flow better. After you have done all of your tweaking, I can put final edits on Application Examples. There will be a couple small things to discuss, but everything is in really good shape now.
