/**
 * Example pay driver
 * 
 * How to create your own pay driver:
 * 
 * <ol>
 * <li>Copy the directory "_local/eshop/pay_drivers/example" to another, i.e. "_local/eshop/pay_drivers/my_driver"</li>
 * <li>Open driver.php in your path and:
 * <ul>
 * <li>Rename driver class name to your name (MyDriver_PaymentSystemDriver). Naming rule: all words delimeted by _ should be started from uppercase letter. Not _ allowed in driver name.</li>
 * <li>In some cases you should to check or add some fields when printing payment button on checkout page. You can manipulate with $aData array in getPayButton method for it. The same for pay system button with autoredirect but the method is getPayButtonParams</li>
 * <li>User will come back to the site from payment system by special URL and system already has the checks for setting correct order status. If you want to make your manual checking do it in payProcess method.</li>
 * <li>For payment system background requests for order approving there is payCallback method. You need to override this method with you own check of payment data.</li>
 * <li>If get or post field are differ from order_id, id or item_number you need to override getProcessOrder method that will return valid order id from POST and GET request.</li>
 * </ul>
 * </li>
 * <li>Open driver.tpl and modify sets:
 * <ul>
 * <li>settings_form - part of form that will be insertted to driver form when you open your driver for editing.</li>
 * <li>checkout_form - button that will be shown on checkout page after the list of items. ##hiddens## field is required.</li>
 * <li>pay_form - form that will be submitted to payment system. In most cases this form is made with autoredirect.</li>
 * <li>Also modify path to driver.lng.</li>
 * </ul>
 * </li>
 * <li>Captions for drivers you can set in driver.lng.</li>
 * <li>After all these steps install your driver in Settings/Pay drivers page of admin panel and edit parameters. Then include your diver for the payment in option "Allowed payment drivers" of Catalog : Orders setting.</li>
 * </ol>
