     * This function may be called from display_guide() to display the whole guide, or it can be
     * called by itself to return a template used by JavaScript to add new empty criteria to the

     * In this case it will use macros like {NAME}, {LEVELS}, {CRITERION-id}, etc.

     * When overriding this function it is very important to remember that all elements of html
     * form (in edit or evaluate mode) must have the name $elementname.

     * Also JavaScript relies on the class names of elements and when developer changes them
