/* The following are the classes that actually make up the individual parts
 * of a web page. They are not elementary, because they usually contain
 * more than one html tag, or have the ability to store other advanced
 * objects. Menus, diffrent layoout parts, the actual top-page class, 
 * news-class, etc.
 * This marks the core of the html.php
 * ====================================================================
 */

/* The basic page. All pages need this. 
 * This could probably be a lot prettier, but this is generic and
 * works quite well.
 * The idea is that diffrent parts of bwreg will simply do 
 * $page->content->add(foo) to add something to the content
 * part, and that it's first come first serve, or CSS handles the order.
 * This will only print info and controlboxes if they have actual content.
 * This in turn makes it trivial to add things to the warn-box without
 * caring about anything except the object that's added in that part of the
 * code. This lets us deal with hiding messages, not the actual box.
