   * The default execute handler fully renders the view.
   *
   * For the simplest use:
   * @code
   *   $output = $view->executeDisplay('default', $args);
   * @endcode
   *
   * For more complex usages, a view can be partially built:
   * @code
   *   $view->setArguments($args);
   *   $view->build('default'); // Build the query
   *   $view->preExecute(); // Pre-execute the query.
   *   $view->execute(); // Run the query
   *   $output = $view->render(); // Render the view
   * @endcode
   *
   * If short circuited at any point, look in $view->build_info for
   * information about the query. After execute, look in $view->result
   * for the array of objects returned from db_query.
   *
   * You can also do:
   * @code
   *   $view->setArguments($args);
   *   $output = $view->render('default'); // Render the view
   * @endcode
   *
   * This illustrates that render is smart enough to call build and execute
   * if these items have not already been accomplished.
   *
   * Note that execute also must accomplish other tasks, such
   * as setting page titles, breadcrumbs, and generating exposed filter
   * data if necessary.
