s13n of page history is just converting all revision data into

http://tw.rpi.edu/proj/semhis.wiki/index.php/Main_Page
Here are some examples of questions that can be answered with s13n of history:
- Show me the edits made by postdocs
- Show me the edits that were commented as 'style improvement'
- Who has changed the first name of James Hendler?
- What kind of properties do users from Category:Developers change mostly?
