title: Where is getChildFragmentManager in support library v13?
body: <p>Android support library v13 is supposed to provide support for newer APIs from Android 3.1. However, as far as I can tell there is no support for child fragments. Specifically, where is getChildFragmentManager()? The v13 support library relies on native fragments, which didn't add this method until API level 17. I have an app with minimum SDK level 14 so I should be able to use the v13 support library, but it seems I can't.</p>
  
  <p>I don't want to go all the way back to the v4 support library and take on all it's weight. The v13 library is perfect otherwise.</p>
