Overall goal is to add a new group of Mongo collections to track usage/user activity on a per-resource basis. 

• views & downloads
  • files
  • datasets
  • collections
• distinction between agents
  • logged in users via GUI and API
  • user API keys
  • extractors
• ability to export simple report
  • per-file statistics
    • bytes
    • path on disk
    • access count (different from simple views)
    • last accessed
  • potentially filter report by "only objects that have been accessed > X months ago" to avoid massive reports
