Book - CodeIgniter for Rapid PHP Application Development (David Upton) Problem

[eluser]Suanko[/eluser]
Hi, I'm having a lot of trouble trying to make the CRUD system in this book to work. I'm not a great expert of codeingiter/php but i usually do ok. My main problem is there is not a full clean exemple of this CRUD, and there is missing Libraries.
For instance, i would very like to know where i can find this :

Code:

$this->load->library('menu');

Which is called here :

Code:

$fred = new menu;

If any of you people have a working sample project with this CRUD model, it would be very welcomed.
Thanks.
