/**
 * Define the recurring payment method/gateway function callbacks.
 *
 * This hook enables payment modules to register that they support
 * ubercart recurring fees and define the callbacks to trigger when
 * a recurring operation is required using the specific payment
 * method or gateway.
 *
 * @return
 *   An array of recurring fee handler items, each fee handler has a key
 *   corresponding to the unique payment method or gateway id. The item is
 *   an associative array that may contain the following key-value pairs:
 *
 *   - "name": Required. The untranslated title of the menu item.
 *   - "payment method": Required. The type of payment method, this needs
 *     to correspond to another recurring fee handler (e.g. credit).
 *   - "fee handler": the unique id of the payment gateway or
 *     another handler that should handle the recurring fee.
 *   - "module": name of the module that implements this fee handler.
 *   - "process callback":  The function to call when setting up the recurring
 *     fee.
 *   - "renew callbak": Function to call when renewing the recurring fee.
 *   - "cancel callback": Function to call when cancelling a recurring fee.
 *   - "own handler": set to TRUE if this recurring handler will be responsible
 *     for processing renewals and not uc_recurring. (Default: FALSE)
 *   - "saved profile": if set to TRUE then this payment method will be
 *     available to other charges.
 *   - "menu": Array of menu items that provide the user operations.
 *     uc_recurring does provide some common default operations for charge,
 *     edit and cancel which can be reused by setting these to either:
 *     - UC_RECURRING_MENU_DISABLED (default)
 *     - UC_RECURRING_MENU_DEFAULT
 *
 * For a detailed usage example, see modules/uc_recurring.test_gateway.inc.
 *
 * ~~~~ We should put some developer docs online somewhere ~~~~
 * For comprehensive documentation on the ubercart recurring system, see
 * @link http:// drupal.org/node/<nid> http:// drupal.org/node/<nid> @endlink .
