/**
 * Pagarme Refund Request
 *
 * This route is used when you want to reverse a transaction
 * performed by a charge via credit card.
 * In case of reversal a transaction, only the id of the transaction
 * is required to effect the reversal.
 *
 * Example -- note this example assumes that the purchase has been successful
 * and that the transaction ID returned from the purchase is held in $sale_id.
 * See PurchaseRequest for the first part of this example transaction:
 *
 * <code>
 *   // Do a refund transaction on the gateway
 *   $transaction = $gateway->refund(array(
 *       'transactionReference'     => $sale_id,
 *   ));
 *   $response = $transaction->send();
 *   if ($response->isSuccessful()) {
 *       echo "Refund transaction was successful!\n";
 *       $refund_id = $response->getTransactionReference();
 *       echo "Transaction reference = " . $refund_id . "\n";
 *   }
 * </code>
 *
