 * Controller class for minifying a set of files

 * E.g. the following would serve the minified Javascript for a site
 * <code>
 * Minify::serve('Files', array(
 *     'files' => array(
 *         '//js/jquery.js'
 *         ,'//js/plugins.js'
 *         ,'/home/username/file.js'
 *     )
 * ));
 * </code>
 * 
 * As a shortcut, the controller will replace "//" at the beginning
 * of a filename with $_SERVER['DOCUMENT_ROOT'] . '/'.
