title: How to start shared element transition using Fragments?
body: <p>I am trying to implement transitions between fragments which have "shared elements" as described in the new material design specs.
  The only method I can find is the <a href="https://developer.android.com/reference/android/support/v4/app/ActivityOptionsCompat.html#makeSceneTransitionAnimation(android.app.Activity,%20android.view.View,%20java.lang.String)">ActivityOptionsCompat.makeSceneTransitionAnimation</a>, which I believe works on Activity only.
  I've been searching for this same functionality but with/for fragments.</p>
