/**
 * <p>
 * This annotation is intended to be used on methods to receive click on menu
 * items.
 * </p>
 * <p>
 * The annotation value should be one or several of R.id.* fields. If not set,
 * the method name will be used as the R.id.* field name.
 * </p>
 * <p>
 * The method may return a <code>boolean</code>, void, or a
 * {@link java.lang.Boolean}. If returning void, it will be considered as
 * returning true (ie: the method has handled the event).
 * </p>
 * <p>
 * The method MAY have one parameter:
 * </p>
 * <ul>
 * <li>A {@link android.view.MenuItem} parameter to know which menu item has
 * been clicked</li>
 * </ul>
 *
 * <blockquote>
 * 
 * Example :
 * 
 * <pre>
 * @EActivity(R.layout.main)
 * @OptionsMenu({ R.menu.my_menu1, R.menu.my_menu2 })
 * public class MyActivity extends Activity {
 * 
 * 	@OptionsItem
 * 	void menuRefreshSelected() {
 * 		// ...
 * 	}
 * 
 * 	@OptionsItem({ R.id.menu_search, R.id.menu_share })
 * 	boolean multipleMenuItems() {
 * 		return false;
 * 	}
