Issues in chapter 3 (Chatbot)

Two issues

1. not able to clone the files by using git clone. Refer page 98 of ROS_ ROBOTICS_PROJECTS
   I was in this directory on my terminal --
   [ /home/niksuvi/catkin_ws/ros_aiml/data ]
   and using the following command and path---
   [ git clone https://github.com/qboticslabs/ros_robotics_projects/tree/master/chapter_3_codes /ros_aiml/data ]

I sorted this by downloading the files and copying in my "data" folder. Did similar for "scripts" and "launch".

2. Secondly launch command is giving an error. After changing permission if i use
   $ roslaunch ros_aiml start_chat.launch
   It says
   [start_chat.launch] is neither a launch file in package [ros_aiml] nor is [ros_aiml] a launch file name
   The traceback for the exception was written to the log file

Hi, i hope you put this package in your ROS workspace and built using catkin_make.

After doing catkin_make, just do $ roscd ros_aiml

to confirm it is properly set.

If it is set, then you can launch the file.

You can change the permission of launch files also.
