/**
 * Array Adapter for {@link Card} model.
 * Use it with a {@link CardGridView}.
 * </p>
 * Usage:
 * <pre><code>
 * ArrayList<Card> cards = new ArrayList<Card>();
 * for (int i=0;i<1000;i++){
 *     CardExample card = new CardExample(getActivity(),"My title "+i,"Inner text "+i);
 *     cards.add(card);
 * }
 * <p/>
 * CardGridArrayAdapter mCardArrayAdapter = new CardGridArrayAdapter(getActivity(),cards);
 * <p/>
 * CardGridView gridView = (CardGridView) getActivity().findViewById(R.id.gridId);
 * gridView.setAdapter(mCardArrayAdapter); *
 * </code></pre>
 * It provides a default layout id for each row @layout/list_card_layout
 * Use can easily customize it using card:list_card_layout_resourceID attr in your xml layout:
 * <pre><code>
 *    <it.gmariotti.cardslib.library.view.CardGridView
 *     android:layout_width="match_parent"
 *     android:layout_height="match_parent"
 *     android:columnWidth="190dp"
 *     android:numColumns="auto_fit"
 *     android:verticalSpacing="3dp"
 *     android:horizontalSpacing="2dp"
 *     android:stretchMode="columnWidth"
 *     android:gravity="center"
 *     card:list_card_layout_resourceID="@layout/carddemo_grid_gplay"
 *     android:id="@+id/carddemo_grid_base1"/>
 * </code></pre>
 * or:
 * <pre><code>
 * adapter.setRowLayoutId(list_card_layout_resourceID);
 * </code></pre>
 * </p>
