title: ViewPager inside ViewPager
body: <p>I would like to create a ViewPager (with three items) where each of its view is another ViewPager (with two items). User then swipe items like this:</p>
  
  <pre><code>ViewPager1[0] ViewPager2[0]
  ViewPager1[0] ViewPager2[1]
  ViewPager1[1] ViewPager2[0]
  ViewPager1[1] ViewPager2[1]
  ViewPager1[2] ViewPager2[0]
  ViewPager1[2] ViewPager2[1]
  </code></pre>
  
  <p>How would that be possible?</p>
