title: Pop to root view when tab is selected
body: <p>I've been having some trouble with something I thought might be easy. I have a table in my root view controller, when a row is selected I push a new view and from there I go to another tab. </p>
  
  <p>My question is how do I make sure that as soon as the user taps the first tab the navigation controller will pop to root? </p>
