Enhance provenance tracking throughout AOP-Wiki system

[jabedini@rti.org]

Improving the provenance for the information in the AOP-Wiki by ensueing uses of the system can Trust the information provided. 

For this, the new wiki data model should support three major features.

• Make it clear who contributed which content. While this information is currently available, it can be laborious to identify all the contributions from a single user using the edit history associated with each page.
  
• Document the strategy used to assemble literature when evaluating the evidence. This requires not only that contributions from individual users are tracked, but the individual references used must be tracked and tied to the strategy used to assemble the literature.
  
• Provide a more consistent format for the information in the AOP-Wiki. Users don’t have time to decipher many different ways of capturing the information. If the provenance of the wiki knowledge is not readily apparent, it will be invisible to most consumers of that information.
