Request: handling multiple object instances of the same type

[mklingen]

Currently simtrack can only support tracking for one instance of a particular object. Could it be extended to support multiple instances of the same object?

Indeed it would be nice if one could detect and track several objects of the same type inside ROS.

I put twice the object in the list of objects to track demo_objects.yaml and it actually shows me the two objects correctly on the /simtrack/image topic, but as both their positions are publish in the same topic it is not straight forward to distinguish one from the other inside the ROS system even if the job since to be done within the software.

Maybe we could publish a markerArray instead ?
