basic skeleton gateway to implement your own gateway credit card implementation according to your gateway API

unzip and replace filenames and instances of “mygateway” as required and place into your plugins directory

read the comments in the files, update/edit/changes as necessary

currently only documented for hosted payment pages (i.e redirection to gateway for payment) – ajax overlay docs will follow in due course

although gateway implementation may change in the future , i will still cater for this way of implementation if at all possible or – at a minimum – update files as necessary
