/**
 * # WooCommerce Payment Gateway Plugin Framework
 *
 * A payment gateway refinement of the WooCommerce Plugin Framework
 *
 * This framework class provides a base level of configurable and overrideable
 * functionality and features suitable for the implementation of a WooCommerce
 * payment gateway.  This class handles all the non-gateway support tasks such
 * as verifying dependencies are met, loading the text domain, etc.  It also
 * loads the payment gateway when needed now that the gateway is only created
 * on the checkout & settings pages / api hook.  The gateway can also be loaded
 * in the following instances:
 *
 * + On the My Account page to display / change saved payment methods (if supports tokenization)
 * + On the Admin User/Your Profile page to render/persist the customer ID field(s) (if supports customer_id)
 * + On the Admin Order Edit page to render a merchant account transaction direct link (if supports transaction_link)
 *
 * ## Supports (zero or more):
 *
 * + `customer_id`             - adds actions to show/persist the "Customer ID" area of the admin User edit page
 * + `transaction_link`        - adds actions to render the merchant account transaction direct link on the Admin Order Edit page.  (Don't forget to override the SV_WC_Payment_Gateway::get_transaction_url() method!)
 * + `capture_charge`          - adds actions to capture charge for authorization-only transactions
 * + `my_payment_methods`      - adds actions to show/handle a "My Payment Methods" area on the customer's My Account page. This will show saved payment methods for all plugin gateways that support tokenization.
 *
 * @version 2.0.0
