  /**
   * Implements Drupal\field\Plugin\Type\Formatter\FormatterInterface::viewElements().
   *
   *
   * Useful values:
   *
   *   $entity->date_id
   *     If set, this will show only an individual date on a field with
   *     multiple dates. The value should be a string that contains
   *     the following values, separated with periods:
   *     - module name of the module adding the item
   *     - node nid
   *     - field name
   *     - delta value of the field to be displayed
   *     - other information the module's custom theme might need
   *
   *     Used by the calendar module and available for other uses.
   *     example: 'date:217:field_date:3:test'
   *
   *   $entity->date_repeat_show
   *     If true, tells the theme to show all the computed values
   *     of a repeating date. If not true or not set, only the
   *     start date and the repeat rule will be displayed.
