/**
 * The goal of this page is to create a CSS association. So firts, what is a css
 * association, and how it works.
 *
 * The idea came that CSS should be broken in small pieces, easily maintanable,
 * instead of one big CSS. So, the user created several little CSS pieces :
 * - css_menu
 * - css_header
 * - css_footer
 * - css_whatever
 *
 * There is a table (css_assoc) on the DB with the following fields :
 * - assoc_to_id  : the id of the element we associate the CSS with
 *            it can be a template id, a page id, a what you want id
 * - assoc_css_id  : the id of the CSS we link
 * - assoc_type    : what do we link the CSS to ? for the moment, only template
 * - create_date  : the create date of this association
 * - modified_date  : the modified date of this association (which is not used
 *            at the moment.
 *
 * This page takes arguments as GET variables. 3 arguments are necessary :
 * - $id    : refers to "assoc_to_id", the id of the element
 * - $css_id  : the id of the CSS we link, refers to "assoc_css_id"
 * - $type    : the type of element $id refers to (only template for the
 *          moment)
