example analysis/"requirements"/about for EOWG docs

Hi, David, William, Henny, Pasquale, Andrew, 

Here are examples of mini "requirements" / analysis for EOWG docs -- the "About" sections of:
* http://www.w3.org/WAI/EO/changelogs/cl-eval-ut
* http://www.w3.org/WAI/EO/changelogs/cl-retrofit
* http://www.w3.org/WAI/EO/changelogs/cl-eval-teams.html
* http://www.w3.org/WAI/EO/Drafts/eval/tools/tools-changelog
* http://www.w3.org/WAI/bcase/changelog

Note that the format is very flexible. Do what you want to quickly & easily jot down what's needed to ensure that we have a shared understanding of the document. Thanks!

Best,
~ Shawn
