To use, save this to app/View/Helper/CustomPaginatorHelper.php, and add something like this in the controller:

class PostsController extends AppController {

    /**
     * Helpers for this controller.
     * @var array
     */
    public $helpers = array('CustomPaginator');

    /**
     * Paginated list of posts.
     *
     * @return void
     */
    public function index() {
        $this->Post->recursive = 0;
        $this->set('posts', $this->paginate());
    }
}

You can then call $this->CustomPaginator->numbers() and all other methods on the original Paginator class in the view templates.
