 * This is a demonstration file that shows a book editing with SmartClient.
 * 
 * Instead of getting data from a database ( which is what your app would use ), we store data on a $_SESSION var.
 * 
 * The $_GET['act'] var define the action that this script will take. We have the following actions:
 * 
 * - List-json: return data listing in json format
 * - Add-json: add data and return a confirmation in json format
 * - Edit-json: update data and return a confirmation in json format
 * - Delete-json: delete data and return a confirmation in json format
 * - Add: create the add form with SCPHP
 * - Edit: create the edit form with SCPHP
 * - List: create grid and datasource with SCPHP
 * - Else: create the window structure
