title: Best way to provide a "tooltip tour"
body: <p>What is the best way to provide a quick tour of a webapp using contextual tooltips?</p>
  
  <p>Use case:</p>
  
  <ul>
  <li>user navigates to the webapp</li>
  <li>some form of popup asking if the user wants a guided tour of the interface</li>
  <li>user can click next on each tooltip to be shown the next one</li>
  <li>user can cancel the tour at any time by clicking some kind of exit X or button</li>
  </ul>
  
  <p>Is there an easy library out there that does this?</p>
  
  <p>Thanks!</p>
