[RADI] wrong path in .launch files for exercises

In the simple_line_follower_ros.launch file placed in
/RoboticsAcademy/exercises/follow_line/launch/simple_line_follower_ros.launch

which has the following code:

<?xml version="1.0" ?>
<launch>
  <include file="/opt/jderobot/share/jderobot/gazebo/launch/f1_1_simplecircuit.launch">
  </include>
</launch>

the file path mentioned here is not valid as opt/jderobot/ has CustomRobots folder due to which if we roslaunch the exercise it throws the error.

RADI is designed for web-templates only. It is not for ROSNode Templates.
Better to follow instructions given here which is Instructions for Web Templates.
