[RADI] wrong path in .launch files for exercises

In the simple_line_follower_ros.launch file placed in

which has the following code:

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