 * Controller class of JSN Data library.
 *
 * To implement <b>JSNDataController</b> class, create a controller file
 * in <b>administrator/components/com_YourComponentName/controllers</b> folder
 * then put following code into that file:
 *
 * <code>class YourComponentPrefixControllerData extends JSNDataController
 * {
 * }</code>
 *
 * The <b>JSNDataController</b> class pre-defines <b>backup</b>, <b>restore</b>
 * and <b>installSample</b> method to handle data backup/restore and sample
 * data installation task. So, you <b>DO NOT NEED</b> to re-define those methods
 * in your controller class.
 *
 * @package  JSN_Framework
