TData_v1.0.py

# TData_v1.0
# Python 3 code to generate test Data project files
# No input arguments required
# System looks to see where it is running from  
# Config.txt file is assumed to be in the root directory along with the source code  
# Data files placed in directory \data - this is platform independent
# Write to a log file as well to screen
