title: Realm java sort with multiple fields
body: <p>I'm sorting like this:</p>
  
  <pre><code>RealmResults&lt;Show&gt; shows = realm.where(Show.class).findAll();
  shows.sort("venueTitle", RealmResults.SORT_ORDER_ASCENDING);
  </code></pre>
  
  <p>How can I sort by multiple properties? Adding another sort line just resets the order of the results entirely.</p>
