In brief:
A. The method is Controller::paginate() and the returned set of
records are passed to the view.
B. Controller::$params['requested'] is set when the action is called
using requestAction. It offers a method of returning data without
requiring that a view is rendered as well.
C. No, $posts is only a paginated set of records. The view would be /
app/views/posts/index.ctp
D. Controller::set() is the method used to pass data to the view.
Essentially, writing compact('posts') is exactly the same as writing
array('posts' => $posts). More on compact() can be found at
http://php.net/compact
