Have way to see which packages need to be reviewed and enhanced

For example, if a package has unknown in the license expression, that package would be a candidate for metadata enhancement.

We need to determine if a package that has been mined and scanned is good as is or needs further review. There are two axis: depth and breadth. Breadth: do we have all the attribute we need (license, copyright, home, etc). Depth: do we have correct data (license clarity, license text and notice etc.)

This should be based on available code in SCTK and should feed a review TODO list.
