title: Ember: Get route instance from the controller
body: <p>I have a multi-step flow that the user can go through sequentially or jump straight to a section (if the sections in between are completed). I think this logic should be in the Route object. However, from within the controller, how do I access the route instance. For example, it would be ideal to be able to do something like this in the controller:</p>
  
  <pre><code>App.Flow = Em.ObjectController.extend({
    submit: function(){
      // Validation and XHR requests
      // ...
  
      // Go to the next step
      route.goToNextStep();
    }
  }
  </code></pre>
