/**
 * An activity representing a list of NewsSources. This activity
 * has different presentations for handset and tablet-size devices. On
 * handsets, the activity presents a list of items, which when touched,
 * lead to a {@link com.vladstoick.stiridinromania.NewsGroupDetailActivity} representing
 * item details. On tablets, the activity presents the list of items and
 * item details side-by-side using two vertical panes.
 * <p/>
 * The activity makes heavy use of fragments. The list of items is a
 * {@link com.vladstoick.Fragments.NewsGroupListFragment} and the item details
 * (if present) is a {@link com.vladstoick.Fragments.NewsGroupDetailFragment}.
 * <p/>
 * This activity also implements the required
 * {@link com.vladstoick.Fragments.NewsGroupListFragment.Callbacks} interface
 * to listen for item selections.
