php cybersource payment gateway integration

This PHP class can be used to process credit card payments via Cybersource.

It can send HTTP requests to Cybersource SOAP Web services API server to  perform several types
of operations to process credit card payments.

Currently it can request a payment authorization, capture the result of a  payment request and
request the reversal of a previous payment request.

This class would require php_soap and php_openssl extensions.
