/**
* This is the index file displayed when a user is logged in on Chamilo.
*
* It displays:
* - personal course list
* - menu bar
* Search for CONFIGURATION parameters to modify settings
* @todo rewrite code to separate display, logic, database code
* @package chamilo.main
* @todo Shouldn't the SCRIPTVAL_ and CONFVAL_ constant be moved to the config page? Has anybody any idea what the are used for?
* If these are really configuration settings then we can add those to the dokeos config settings.
* @todo move display_courses and some other functions to a more appripriate place course.lib.php or user.lib.php
* @todo use api_get_path instead of $rootAdminWeb
* @todo check for duplication of functions with index.php (user_portal.php is orginally a copy of index.php)
* @todo display_digest, shouldn't this be removed and be made into an extension?
