Executing the program is not user-friendly

It seems slightly unclear as to how to actually execute the INITIATOR_SET program. The process listed on the readme is incomplete and incorrect: you need to run the program w/ python3 instead of python (which defaults to Python 2), and it's unclear which .py script to actually run.

A couple of suggestions:

1. edit the readme to replace python [runnable script] with python3 initiator_set/main.py
2. create a run.sh file to combine steps 3-5
