/**

 * If you want it in another position, put a comment like that
 * <pre>
 * // Class and Function List
 * </pre>
 * The script lookup for the string 'Class and Function List' in a comment and replace the entire comment with the list
 * The settings are
 * - list_functions: List functions (0 or 1). Default:1
 * - list_classes:   List classes (0 or 1).   Default:1
 * @todo List functions inside classes as methods
