Feature request

Using Simple Commander API for multi robot systems. This is in continuation to this post.

Feature description

I am making a multi-robot simulation and for my purposes, I want to use the Python API to send navigation goals to different robots. As of now, I cannot see how to do that with two robots(that is add a namespace and setting up goal poses as well as set initial poses individually for each robot). Any guidance on how to do this would be helpful.

Implementation considerations

I think the solution proposed in the post mentioned earlier sounds good, if not implemented yet.
