avoid ROS environment requirement via roslibpy

[jf---]

What's interesting is that roslibpy offers a viable route of working with ROS without having the requirement of running in a ROS environment. Those environments that work with ROS, -well basically Ubuntu linux- are quite a small subset from those environments that run python well.

I think a powerful use case of this project is having a ROS docker running somewhere, and using jupyter-ros to interface it, without having to create the actual ROS environment.

Might be worth looking into it, or to decide whether a ROS env is a requirement or not

roslibpy is using web sockets with ros bridge. for roslibpy will work, you need also install:
sudo apt install ros-melodic-rosbridge-server
and run:
roslaunch rosbridge_server rosbridge_websocket.launch

This will be wonderful if Jupiter ros will add support in roslibpy because it working inside google colab, not as rospy lib.
