Install dlib and face_recognition on a Raspberry Pi

Instructions tested with a Raspberry Pi 2 with an 8GB memory card. Probably also works fine on a Raspberry Pi 3.

Download the latest Raspbian Jessie Light image. Earlier versions of Raspbian won't work.

Write it to a memory card using Etcher, put the memory card in the RPi and boot it up.

Pre-reqs:

Have Python 3 installed. On macOS, this could be installed from homebrew or even via standard Python 3.6 downloaded installer from https://www.python.org/download. On Linux, just use your package manager.
On macOS:
- Install XCode from the Mac App Store (or install the XCode command line utils).
- Have homebrew installed
On Linux:

	A Hack to remote control Spotify from Racket.

	It pretty reliably will crash DrRacket if run.
	Works better if require'd from another module, or run from command line.

	#lang scribble/doc

	Okay, we've made a package and up loaded. But you know what would be lovely?.
	Docs! This tutorial is going to start assuming you have a blank file and now clue where to start. By
	the end we will have written the documentation for this line-of-best-fit library <show>.

	This is racket land, so of course we have a language for documentation! #lang scribble/doc
