Create a Basic Flask Development Environment

This tutorial walks you through setting up the tools you need to begin developing in Python and Flask. Note: I assume you are on a Unix environment (OSX, Linux, Linux VM on Windows).

What you need

Python 2.7.x
easy_install and pip
Git 1.7/1.8
virtualenv

	/*
	1. Download and run https://raw.githubusercontent.com/esp8266/Arduino/master/libraries/ESP8266WiFi/examples/BearSSL_CertStore/certs-from-mozilla.py
	2. Make sure the `certs.ar` file is in the `data/` directory in your project.
	3. Download and install ESP8266LittleFS (see https://arduino-esp8266.readthedocs.io/en/latest/filesystem.html#uploading-files-to-file-system)
	4. Run Tools > ESP8266 LittleFS Data Upload
	5. Upload this sketch

	There are many already existing powerful http servers that can be used in python e.g. gevent, twisted web server. However, they are a bit complex to use and you cannot start them in a thread other than the main thread.

	Here is a sample of basic http server using "BaseHTTPRequestHandler". The example exposed two rest interfaces:

	To ingest records into the web server
	To retrieve already ingested records from the web server
	The records are assumed to be JSON based, however, any type of records can be ingested.
