/**
 * Card Expand model.
 * <p>
 * You can customize this component. See https://github.com/gabrielemariotti/cardslib/tree/master/doc/EXPAND.md for more information.
 * </p>
 * You can easily extend and customize this class providing your inner layout and
 * setting your values with {@link #setupInnerViewElements(android.view.ViewGroup, android.view.View)} method.
 * </p>
 * <b>Usege example:</b>
 * <pre>
 * <code>
 *  //This provide a simple (and useless) expand area
 *   CardExpand expand = new CardExpand(getContext());
 *
 *  //Set inner title in Expand Area
 *  expand.setTitle(getString(R.string.demo_expand_basetitle));
 *
 *  //Add expand to card
 *  card.addCardExpand(expand);
 * </code>
 * </pre>
 * </p>
 * <b>Custom example:</b>
 * <pre>
 * <code>
 * public class CustomExpandCard extends CardExpand {
 *
 *
 *    public CustomExpandCard(Context context) {
 *       super(context, R.layout.carddemo_standard_inner_expand);
 *    }
 *
 *    public void setupInnerViewElements(ViewGroup parent, View view) {
 *
 *         if (view == null) return;
 *
 *         //Retrieve TextView elements
 *         TextView tx1 = (TextView) view.findViewById(R.id.carddemo_expand_text1);
 *         TextView tx2 = (TextView) view.findViewById(R.id.carddemo_expand_text2);
 *         TextView tx3 = (TextView) view.findViewById(R.id.carddemo_expand_text3);
 *         TextView tx4 = (TextView) view.findViewById(R.id.carddemo_expand_text4);
 *
 *         //Set value in text views
 *         if (tx1 != null) {
 *           tx1.setText(getContext().getString(R.string.demo_expand_customtitle1));
 *         }
 *    }
