Adds PayWay payment option to the checkout module.
NOTE: This module requites CURL and the PHP CURL extensions and the mcrypt extension.
Either install via composer:
i-lateral/silverstripe-checkout-payway: *
Or download and install to the "checkout-payway" directory in your project root.
Once installed, go to global site settings, then the "Checkout" tab.
Under payment methods, click "Add" and then select "Payway" from the dropdown.
