/**
 * @file
 * Provides dependent visibility for form items in CTools' ajax forms.
 *
 * To your $form item definition add:
 * - '#process' => array('ctools_process_dependency'),
 * - '#dependency' => array('id-of-form-item' => array(list, of, values, that,
 *   make, this, item, show),
 *
 * Special considerations:
 * - Radios are harder. Because Drupal doesn't give radio groups individual IDs,
 *   use 'radio:name-of-radio'.
 *
 * - Checkboxes don't have their own id, so you need to add one in a div
 *   around the checkboxes via #prefix and #suffix. You actually need to add TWO
 *   divs because it's the parent that gets hidden. Also be sure to retain the
 *   'expand_checkboxes' in the #process array, because the CTools process will
 *   override it.
