- Score upload form supports identification of a user based on clicker ID,
  for Course Coordinators who prefer not to use LON-CAPA's in-built
  "Process Clicker" utility.
- clickers.db file on a library server contains key = value pairs, where key
  is (escaped) clicker ID, and value is (escaped) comma-separated list of
  usernames who registered that particular clicker ID.
- bi-nightly run of searchcat.pl will update clickers.db file.
