title: Devise logged in root route rails 3
body: <p>Heyya <strong>guys</strong>.
  So i thought about this coolio idea, if you are logged in then you get some sort of dashboard, else you get an information/login/sign up page.. So how do i do that.. </p>
  
  <p>I mostly wants to do this in Routes = not something like</p>
  
  <pre><code>
  def index
    if current_user.present?
      render :action => 'logged_in'
    else
      render :action => 'logged_out'
    end
  end
  </code></pre>
  
  <p>thanks in advance!</p>
