Install some of the needed python packages

In order to run:

list_users_in_course_with_students_email.py 11

I had to install the following packages with "pip install":

• requests
• pandas
• lxml (note that this is not actually needed by the above program, but it is used in some other programs)
• xlsxwriter

In order to install NumPy (which is required by pandas), I had to install Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools Links to an external site.. After installing Visual C++ you have to do a system restart.

 As I had loaded python 3.6, I had to change the first line of my python program to use python3.6 rather than python3.4.
