NetBanx. createCard() method

>Btw, in the interest of maintaining compatibility with the rest of the library, it might be worth adding a createCard() method which simply processes an authorize transaction for $1.00 and returns a cardReference instead of transactionReference. That way shopping carts which rely on generic gateway functionality would be able to use it. Not a major issue though, just a nice to have.

Not sure I understood you correctly, so please review.
