title: How to use Polymer's paper-tabs
body: <p>I'm just begin using Polymer to design my web, and I have some trouble with it.</p>
  
  <p>Take a look at this: 
  <a href="http://zirox.freevnn.com/newMaterialdesign.html" rel="nofollow">http://zirox.freevnn.com/newMaterialdesign.html</a></p>
  
  <p>I want to switch to another site when I tab/click the tab's name.</p>
  
  <p>Please help.
  Thanks</p>
