4.7. Installing the MathService.rpy script
The finished MathService can be installed directly as an "rpy" script in the "services sub-directory where the service container is executed.
The service container above appears to have only a MathService, but other services that are transparent to the user such as SubscriptionManager and NotificationProducer are configured in the server-config.tac file.

- extra line to create the resource so twisted will recognize it as such.
