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