* Class CheckOutModule - a module for the checkout process
* This class provides a central page module with four modules that make
* up a four part checkout process.
*
* The first part displays the shipping options information to the user with sections
* for choosing addresses and shipping methods.
*
* The second part shows payment options and billing address.
*
* The third part shows the order again and all of the choices with
* final charges and a confirmation action - the user may also choose to
* return to a previous step to modify the quantities in the order or other selections
* (addresses, shipping method, payment, etc.). Note that if they choose to modify
* the quantity they are redirected to the ShoppingCartView page and must
* reinitiate the checkout process (by clicking "Check Out").
*
* The final module confirms the status of the payment and displays misc confirmation
* messages.
*
*@todo
* - send order email confirmation
* - PayPal Express checkout button and action on CheckOutEditModule panel, this
* will basically call the paypal payment action, ie. it should behave like clicking the
* "purchase" button in the PaymentModule ..
