====== Connecting to remote ROS master ======
E.g. my IP is 192.168.0.19 (looked up by running ''ifconfig'') \\
The IP of the machine running ROS master is 192.168.0.8.

On my machine:
<code>
export ROS_IP=192.168.0.19
export ROS_HOSTNAME=$ROS_IP
export ROS_MASTER_URI=http://192.168.0.8:11311
</code>

On the remote master:
<code>
export ROS_IP=192.168.0.8
export ROS_HOSTNAME=$ROS_IP
export ROS_MASTER_URI=http://192.168.0.8:11311
</code>

If I then run ''rostopic list'', I should be able to list the remote ros topics.
