title: CakePHP sanitize utils
body: <p>I can't get it works in my controller. The code is:</p>
  
  <pre><code> App::import('Sanitize');
   class MyController extends AppController
   {
         public $uses = array('Sanitize');
         function Foo()
         {
               // Fatal error: Class 'Sanitize' not found
               $test = Sanitize::paranoid($data);
               // Fatal error: Call to a member function paranoid() on a non-object
               $test = $this-&gt;sanitize-&gt;paranoid($data);
         }
   }
  </code></pre>
  
  <p>What have I missed?</p>
