Casper Purity Checker LLL Walk-through

WARNING: These are notes and are not complete, they may contain errors. They certainly contain awkward language (sorry).

These are my notes from reading the Casper LLL Purity Checker currently being reviewed here: ethereum/casper#143

Specifically, the casper/contracts/purity_checker.py file.

	# first_trades is a dict of the date of the first trade of each market on Poloniex.
	# Values are specified as unix timestamps in whatever timezone the Poloniex API assumes.
	# If you run into timezone issues, my system is GMT+10 (with daylight saving) when creating this.
	#
	# This data is very useful if you're attempting to pull the history of Poloniex's trades.

	BTC_BCN=1400591380.0,
	USDT_NXT=1424337662.0,

	# This fish script will re-tag all the $SRC_TAG_PREFIX images with the
	# $DEST_TAG_PREFIX and push those images to Dockerhub.
	#
	# This script is specifically designed for the github.com/sigp/lighthouse
	# repos, as they exist in April 2023.
	#
	# Be sure to double check the images after you've pushed them, especially the
	# mainfests. I ran this script twice because I kept pulling outdated manifests,
	# I'm not sure if that's a caching issue or if the script needs to be run
	# twice. Running it twice shouldn't hurt.
