/**

|
* Singleton service acting as glue between the DOM APIs and the payment dialog UI.
|
|
*
|
|
* Communication from the DOM to the UI happens via the nsIPaymentUIService interface.
|
|
* The UI talks to the DOM code via the nsIPaymentRequestService interface.
|
|
* PaymentUIService is started by the DOM code lazily.
|
|
*
|
|
* For now the UI is shown in a native dialog but that is likely to change.
|
|
* Tests should try to avoid relying on that implementation detail.
