/**
|
|
* Function library for the links tool.
|
|
*
|
|
* This is a complete remake of the original link tool.
|
|
* New features:
|
|
* - Organize links into categories;
|
|
* - favorites/bookmarks interface;
|
|
* - move links up/down within a category;
|
|
* - move categories up/down;
|
|
* - expand/collapse all categories;
|
|
* - add link to 'root' category => category-less link is always visible.
|
|
*
|
|
* @author Patrick Cool, complete remake (December 2003 - January 2004)
|
|
* @author René Haentjens, CSV file import (October 2004)
