title: Cucumber: Access current controller instance within step definitions
body: <p>I'd like to access the controller instance in my cucumber step definitions.  The purpose of this is so I can manipulate http cookie and session values.  I'm pretty sure there's a way to do this via World, but I'm not sure how.</p>
  
  <p>In regards to Ryan's comment, I'm writing a feature for a page which requires a logged in user (via Authlogic).  I know the cucumber way is to go to the login page and login a user before continuing.  However, I'm using OpenID and have been having trouble orchestrating the process. Regardless, I'd like to avoid that step in writing my feature.  The feature isn't that a user can go to the login page and login <em>then do something</em>; it's what the user can do once they're logged in. </p>
  
  <p>Thanks,</p>
