User authentication system

Your task is now to create a user authentication system.

This document will guide you through all the features and implication of such system, so that you don't have to search them yourself.

We will focus on web/browser-technologies, however similar concept can be widely applied. This guide, is a work in progress, feel free to comment and provide feedbacks.

	# First, we need to find our device. BEFORE inserting your USB drive, run the
	# following:
	diskutil list

	# This will output a bunch of info about all of the disk drives connected to
	# your Mac. Each entry will have a header in the form "/dev/diskX", where X is
	# some number starting at 0. Now, insert your USB drive and run the command
	# again. You should see a new entry. Make note of the name (ie, /dev/diskX).

	Package fan is a little concurrent io experiment.

	Example Use Case
	----------------

	You have a function that takes a single io.Reader as an argument. You would like
	to pass that reader to several processing functions. You could just make the
	function accept an io.ReadSeeker, invoke each function serially in a for loop,
	seeking after each call. But that's not cool.

	Add the `replication` section to the mongod.conf file:

	```
	$cat /usr/local/etc/mongod.conf
	systemLog:
	destination: file
	path: /usr/local/var/log/mongodb/mongo.log
	logAppend: true
	storage:
	engine: mmapv1

	# Meant to work with strings as keys.

	class MyHash
	def initialize(size: 100)
	@size = size
	@hash = Array.new(size)
	end

	attr_accessor :hash

	import "bytes"

	func StreamToByte(stream io.Reader) []byte {
	buf := new(bytes.Buffer)
	buf.ReadFrom(stream)
	return buf.Bytes()
	}

	func StreamToString(stream io.Reader) string {
	buf := new(bytes.Buffer)
