Class 'CI_Formgenerator' not found in C:\Users\mycode\system\core\C

I don't have an application/core folder. According to http://www.codeigniter.com/user_guide/ge...aries.html you put it in your application/libraries folder. I've tried to keep things as "standard" as possible so the location of the file is application\libraries\Formgenerator.php with the following start to my code:

Code:

class Formgenerator {
        
        private $form_output = '';
        
        public function __construct($form_name){
        $ci = get_instance();
