modifying BaseController.php for libraries

I am trying to autoload libraries in BaseController.php. Is DoNotEditThisLine really just a comment?


public function initController(RequestInterface $request, ResponseInterface $response, LoggerInterface $logger)
    {
        // Do Not Edit This Line
        parent::initController($request, $response, $logger);   <<this line is causing an error. Is this really just a comment?

        // Preload any models, libraries, etc, here.
        protected $libraries=[
        'grocery_CRUD',
        'email',
        'image_lib',
        'image_CRUD',
        'ftp',
        'form_validation'
    ];
    }
