Unsender 83e28b2536
Made repo 
- Tried to make the README.md instructions as user friendly as possible.
  - Covers the PGP aspect which did need explaining.
  - Mentions the need for software hygiene.
- Folder structure in git repo is better than current 'tar' file structure.
  - Git repo structure TO BE ADOPTED for any future version

## UPGRADING FROM dfca_0.1.0
## =========================
##
## Please mark this file as executable with:
# chmod +x UPDATER.sh
##
## ... and then update easily by running:
# . UPDATER.sh
##
## In this upgrade, we fix SPACEX' list of IP address ranges to not
## provide false positive warnings in the 8.0.0.0/9 range, let's
## thank a fediverse user at gnulinux.social for discovering this.
## We also add an icon to easily identify AKAMAI connection
## requests, add ALIBABA and TENCENT as DIGITAL FEUDALISTS (I came
## across ALIBABA's ASN by accident. They happen to serve
## 'tesla.io'), and apply the performance improvement to IPv6.
##
## Updating SPACEX IP ranges is trivial with instructions already
## written for such a predictable occurance. Adding ALIBABA and
## TENCENT is less trivial but still easy by using the following
## commands in your bash terminal. Some commands that start with
## 'sudo' will require (su)per user privileges.
##
## The easy steps to do it all...
##
secureFolder="/usr/bin/law-DFCA/"
## Checks that you are in the correct directory to start.
