adding an iterations field to hasDroneAux so we recurse up to three times
no longer subscribe to cmd_vel and remap in launch file, just subscribe to /cmd_vel_mux directly
ok we can launch without syntax errors now
merged the class in velocityDrone since they serve the same purpose
depracated - I will probably remove soon
we can now launch the project via ROS and see the turtlebot perform random walking
