Nugget: Jini LookupLocator

	LookupLocator

	How to find a lookup service by host and port.

LookupLocator

	Each instance of this class represents one lookup service. The host and port are accessible from the instance. This class is instantiated by providing an URL string like `"jini://localhost:4160"`. If the port is omitted, port 4160 (the port reggie listens on) is assumed. During instantiation, the class contacts the host:port and establishes a service connection. This is called performing unicast discovery. To interact with the lookup service, send the message `getRegistrar()` to the instance. The ServiceRegistrar object that is returned is used to issue all service requests to the lookup service.
