Additional Features for extension

[steveamaza]

The Magento Extension for Paystack needs some improvements to make it operate at full capacity. Some of these features are

• Support Magento Instant Purchase for One Click Checkout
• Provide customers option of storing payment information for future transactions using charge authorization.
• Stored customer card information can be used for orders created in the frontend or backend.
• Stored cards deleted by customer in Magento are also deactivated from the merchant's integration using the Deactivate Authorization endpoint.
• Full and partial refund support when creating credit memos.

An example of an extension that implements this is https://github.com/pmclain/module-stripe
