* This callback is mapped to the path

* The arguments in brackets are passed to this callback from the page URL.
* The placeholder names "first" and "second" can have any value but should
* match the callback method variable names; i.e. $first and $second.
*
* This function also demonstrates a more complex render array in the returned
* values. Instead of rendering the HTML with theme('item_list'), content is
* left un-rendered, and the theme function name is set using #theme. This
* content will now be rendered as late as possible, giving more parts of the
* system a chance to change it if necessary.
*
* Consult @link http://drupal.org/node/930760 Render Arrays documentation
* @endlink for details.
*
* @param string $first
* A string to use, should be a number.
* @param string $second
* Another string to use, should be a number.

* @throws \Symfony\Component\HttpKernel\Exception\AccessDeniedHttpException
* If the parameters are invalid.
