  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
