Answer 1

Yes, load is a property. Think of it like this:

class Loader {
    public function view() {
        //code...
    }
}

class MyClass {
     private $load;

     public __constructor() {
         $this->load = new Loader();
     }

     public someMethod() {
         $this->load->view();
     }
}

This syntax is called chaining.

Your controller inherits CI_Controller. So, if you look in application/system/core/Controller.php you'll find something interesting : $this->load =& load_class('Loader', 'core'); (l.50 with CI2). So, $this->load refer to the file application/system/core/Loader.php which have a function public function view (l.418 with CI2)
