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.

Let's say that you're building a new feature, called 'new-button' which changes the color of buttons, which is currently red, to blue. Then you'd change code that looks like this -

	const cp = require('child_process')

	/**
	* A function that spawns a new process using the given command, logging the stdout and stderr.
	*
	* @param {String} command
	* @param {Array} args
	* @return {Promise}
	* @example
	*

	class AbortError extends Error {
	name = "AbortError";
	message = "Aborted";
	}

	class AbortSignal extends EventTarget {
	aborted = false;
	}

	class AbortController {
