/**
* Class PaymentModule - a module to manage PaymentMethods
*
* This class iterates through the list of PaymentMethods in the payment_methods table
* and for each that is flagged active it creates a QRadioButton to be rendered in the template.
* When the button is clicked, it sets objSelectedMethod to the selected payment method.
* When the 'Purchase' button is clicked the btn_Purchase function is called; this calls three
* functions that a PaymentAction is required to implement:
*   - PreProcess: perform any actions to set up the transaction
*   - Process: perform the actual transaction, ie. connect to server and make a request in most cases.
*   - PostProcess: perform any validation checks and update the order_status_history table in most cases.
