  18  * Public Profile -- a user's public profile page
  19  *
  20  * - each user can currently have their own page (cloned from system and then customised)
  21  * - users can add any blocks they want
  22  * - the administrators can define a default site public profile for users who have
  23  *   not created their own public profile
  24  *
  25  * This script implements the user's view of the public profile, and allows editing
  26  * of the public profile.
