[ROS in 5 mins] 006 - What Is A ROS Node? Turtlesim Node Example

Again, let's see what a ROS node is in just 5 minutes. We'll see the example of the turtlesim node - how to launch it, what it does and some commands to get basic and extended information about the ROS node:
* rosnode list
* rosnode info
