  /**
   * To make a form auto submit, all you have to do is 3 things:
   *
   * ctools_add_js('auto-submit');
   *
   * On gadgets you want to auto-submit when changed, add the ctools-auto-submit
   * class. With FAPI, add:
   * @code
   *  '#attributes' => array('class' => 'ctools-auto-submit'),
   * @endcode
   *
   * If you want to have auto-submit for every form element,
   * add the ctools-auto-submit-full-form to the form. With FAPI, add:
   * @code
   *   '#attributes' => array('class' => 'ctools-auto-submit-full-form'),
   * @endcode
   *
   * Finally, you have to identify which button you want clicked for autosubmit.
   * The behavior of this button will be honored if it's ajaxy or not:
   * @code
   *  '#attributes' => array('class' => 'ctools-use-ajax ctools-auto-submit-click'),
   * @endcode
   *
   * Currently only 'select' and 'textfield' types are supported. We probably
   * could use additional support for radios and checkboxes.
