 * Stripe Capture Request.

 * Use this request to capture and process a previously created authorization.
 *
 * Example -- note this example assumes that the authorization has been successful
 * and that the authorization ID returned from the authorization is held in $auth_id.
 * See AuthorizeRequest for the first part of this example transaction:
 *
 * <code>
 *   // Once the transaction has been authorized, we can capture it for final payment.
 *   $transaction = $gateway->capture(array(
 *       'amount'        => '10.00',
 *       'currency'      => 'AUD',
 *   ));
 *   $transaction->setTransactionReference($auth_id);
 *   $response = $transaction->send();
 * </code>
