Detailed Description

Abstract base class for a service from which you can query a port range by name and receive a PortRange object.

The goal of this class is to split up the port space into chunks, each of which is assigned to a particular kind of service. When dealing with dynamic service creation, this allows us to avoid the situation where a service goes down and a different kind of service starts listening on its port, confusing anything that was connected and didn't know immediately about the change.
