Python zipapp web apps

This concept is very much like .jar or .war archives in Java.

NOTE: The built .pyz zipapp can run on both Python 2 & 3 but you can only build .pyz zipapps with Python 3.5 or later.

Johan Beyers has a great list of resources as well. http://johan.beyers.co.za/pages/resources.html

	# IMPORTANT!
	# At the moment this script is forged only for Debian ( tested on 8.x release ).
	# Although my efforts were put on building this also on Arch Linux or Alpine, at the moment only Debian seems to be able to build it.
	# Also, not sure why these instructions where nowhere on the internet, therefore I leave them here for whoever need them.

	Python script for batch geocoding of addresses using the Google Geocoding API.
	This script allows for massive lists of addresses to be geocoded for free by pausing when the
	geocoder hits the free rate limit set by Google (2500 per day). If you have an API key for paid
	geocoding from Google, set it in the API key section.
	Addresses for geocoding can be specified in a list of strings "addresses". In this script, addresses
	come from a csv file with a column "Address". Adjust the code to your own requirements as needed.
	After every 500 successul geocode operations, a temporary file with results is recorded in case of
	script failure / loss of connection later.
	Addresses and data are held in memory, so this script may need to be adjusted to process files line
