/**
 * Called to have the fragment instantiate its user interface view.
 * This is optional, and non-graphical fragments can return null. This will be called between
 * {@link#onCreate(Bundle)} and {@link#onViewCreated(View, Bundle)}.
 *<p>A default View can be returned by calling {@link#Fragment(int)} in your
 * constructor. Otherwise, this method returns null.
 *
 *<p>It is recommended to<strong>only</strong>inflate the layout in this method and move
 * logic that operates on the returned View to {@link#onViewCreated(View, Bundle)}.
 *
 *<p>If you return a View from here, you will later be called in
 * {@link#onDestroyView} when the view is being released.

 *@paramsavedInstanceStateIf non-null, this fragment is being re-constructed
