Subscriber (Sim0MQ demo classes 2.00.04 API)

java.lang.Object
- org.sim0mq.test.pubsub.Subscriber

```
public final class Subscriber
extends Object
```
The PUB-SUB pattern takes place on port 9001. Port 9002 is used in a PAIR-PAIR setting to start the publisher when the subscriber comes on-line and terminate the publisher after the subscriber has received 100 messages. The message can be coded as one string, but in this casse it is coded as two separate frames, where the first frame is the subscription topic.
