Here is a list of what I modified:
+ Use the today command to show the date when I last modified this document.
+ Put the dates on the right hand side, instead of at the beginning of each row.
+ Add a contents section. This is recommended for a document with more than 10 pages.
+ Add the page number at the bottom right of each page.
+ Utilize the input command to add a section directly from another .tex file. When each section is long, this keeps the master document short and easy to maintain.
