/**
|
|
* Main script for the links tool.
|
|
*
|
|
* Features:
|
|
* - Organize links into categories;
|
|
* - favorites/bookmarks-like interface;
|
|
* - move links up/down within a category;
|
|
* - move categories up/down;
|
|
* - expand/collapse all categories (except the main "non"-category);
|
|
* - add link to 'root' category => category-less link is always visible.
|
|
*
|
|
* @author Patrick Cool, main author, completely rewritten
|
|
* @author René Haentjens, added CSV file import (October 2004)
|
|
* @package chamilo.link
|
|
* @todo improve organisation, tables should come from database library
|
|
* @todo Needs serious rewriting here. This doesn't make sense
