Feature flags

This is my own writeup on feature flags; for a deep dive I'd recommend something like Martin Fowler's article (https://martinfowler.com/articles/feature-toggles.html).

So. Feature flags. The basic idea that you'll store configuration/values on a database/service somewhere, and by changing those values, you can change the user experience/features for a user on the fly.

	Hello, I'm glad you contacted me asking for help. In order to help you help
	yourself I have crafted this fine little automated email with information and
	things you should try before asking for help. When you run into a problem I
	want you to do the following things before you email me, and then email me your
	answers. Doing this will most likely help you solve the problem on your own,
	and will save me time in the long run. If after doing this you are truly
	stuck and you can answer all these questions then email me your answers and
	I'll help you.

	// NOTE: the '#form-id' selector below will most certainly be different
	// for whatever page you're on. Remember to change it in both instances!

	// run this in the terminal to save the state of your form
	// in your browser's LocalStorage:
	[].forEach.call(document.querySelector('#form-id').elements, function(el) {
	localStorage.setItem(el.name, el.value);
	});

	// then refresh the page and run this to restore your form values:

	# You will learn why `make` is so great, and why, despite its "weird" syntax,
