## python batch geocoding.py
"""
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

    LTC-Lightning-Network-lnd-Guide

This is a step-by-step main net tutorial on how to setup a Lightning Network node for Litecoin on a Mac. It is specifically for the lnd client by the Lightning Labs.  You can copy and paste most of the commands except for the times I've indicated in bold for you to input your own information.  It would also be a good idea to backup your computer prior to starting just in case you need to start over.
Below is a legend.  Refer to it as you come across terms or symbols you don’t understand.  The first part of the tutorial is taken from the lnd github.  However, everything else is written with the help of Patrick Walters taking me step by step through the process.
Legend

$ = This symbol means 1 line of code.  Do not type “$” into your terminal.  Simply input what follows then push enter.
Pubkey = Short for the public key that is generated from the private key w
