Changes made between version 2.0 and 1.0
The major change was moving the content from a Microsoft Word document to a Wiki. This transition allowed for content to be accessed on a section by section basis, easy cross-referencing of each section, and the ability to easily determine not only how many times a section is referenced, but also where. Specifically:
