title: R shiny navbarPage right aligned tabs
body: <p>By default, using <code>navbarPage()</code> in shiny creates a 'static top' bootstrap page (<a href="http://getbootstrap.com/examples/navbar-static-top/" rel="nofollow">example</a>).  If I were writing the html for a webpage, I could add a <code>&lt;ul&gt;</code> element with a class of <code>nav navbar-nav navbar-right</code> where the <code>navbar-right</code> would move the tabs/menus to the right side of the navbar.</p>
  
  <p>There doesn't seem to be a way to coerce this behavior directly through the framework - is there a clever known way to accomplish this?</p>
