Node Graph - Same Topic, Different Domains

[brianr114]

I suspect both will show up in the same topic chart, which might be ok. A nice feature might be able to differentiate between two domains.

Test results:
Squares on Domains 0 and 1. They do in fact plot on the joint graph. Maybe a nice feature would be to indicate on graph which domain each pair of nodes is in. Would require reading in another property from tshark (rtps.domain_id)
