fakeUserCSV.py

# This program makes a list of random names, ID numbers and email's which resemble the actual username
# The purpose of this file is to create dummy data which can be used to run benchmark testing on databases 
# This code is a horribly and quickly implemented hack to solve a problem for a student.
#
# the names were taken from here: https://stackoverflow.com/questions/1803628/raw-list-of-person-names
# The technique I used to replace odd characters is so, so, so very ugly and silly
# however, the actual code isn't mine. https://stackoverflow.com/questions/3411771/multiple-character-replace-with-python
#  

# TODO: the ID's can possibly duplicate. fix to ensure they are unique.
