Refund and capture functions in Shop-Script

Hello All,

I am developing an payment plugin for Shop-Script and I have some questions.

I see "waIPaymentCapture", "waIPaymentRefund" interfaces and capture(), refund() methods so:

1. Does Shop-Script support refund, capture after payment?

2. If yes, how to use and develop this function. Ex: I can click on the capture button in the order and it will process capture following my source code.

Thank for your advices.
