Example - expose topics

[sshanks-kx]

For the producer.q - may be handy to print topic being used or provide a topic
Quickly ran the example with the solace subscriber & took a min to figure out the topic I should be subscribing to, in order to see the data.

Example running, just for show:
q producer.q
(msgsent;1) (msgsent;2)
(`msgsent;3)

subscribing to topic2
