Needed for Flask app:
- flaskblockchain.py: Needs to run the app, and provide handlers for http requests
- Config.py: Defines environment variables for different execution environments, to turn on and off different functionalities or logging levels. Not strictly required, but useful for having both development and deployment environments
- .env: Source this to set environment variables
- requiremens.txt: Generated by
pip freeze > requirements.txt
Required for Heroku:
- runtime.txt: Specify the Python runtime environment
- Procfile: Required by Heroku to indicate the type of dyno to spin up, and what to run

- In addition to installing Flask and other requirements, be sure to install
