title: How to set "TabsStyle.Hidden" property on TabbedPage
body: <p>In Xamarin.Forms, I'm using a <code>TabbedPage</code>, but I wanted the tab navigation to be hidden.</p>
  
  <p>There is an enum <code>TabsStyle</code>, with following options:</p>
  
  <ul>
  <li><strong>Default:</strong>  Tabs are placed and displayed according to system defaults.</li>
  <li><strong>Hidden:</strong>   Tabs are hidden.</li>
  <li><strong>Icons:</strong>    Tabs are shown as icons.</li>
  <li><strong>OnBottom:</strong> Tabs are displayed at the bottom of the page.</li>
  <li><strong>OnNavigation:</strong> Tabs are displayed when the user swipes from a screen edge.</li>
  </ul>
  
  <p>But I can't seem to find any reference on where to set this property. Where do I set it? How to hide the tab navigation on a TabbedPage?</p>
