I think maybe he means something like the Layout library where one can insert something like $this->layout->view('home') in a controller and have the home.php page content wrapped around a template. Similar to what some people do with including a header.php and footer.php file but I always found the 1 layout file cleaner and easier to manage.
I use the Layout library a lot. I pretty much re-packaged my clean CI install to include the Layout library. So now, I have a layouts folder in my views folder. Then I can make a default.php layout and an admin.php layout. The default.php layout loads automatically and when I want to use admin.php, I put $this->layout->set_layout('admin') in the controller.
It works good for certain layouts that require TinyMCE too.
