/// This propety wrapper generates a variable that is backed by UserDefaults.

/// At initialization, you supply the key at which the the variable will be
/// saved, and the instance of UserDefaults in which to save it.

/// Like any other variable, it can be made get-only using `private(set)`, to

/// The NonNil property wrapper allows you to supply an error message at the declaration of a
/// property, and then otherwise access it like it's non-nil in your code. Any access before it's
/// set will still result in a crash the way explicity unwrapping would, but with the added benefi
/// of there being an informative crash message. Intended to be a conscientious and thoughtful
/// replacement for the `!` operator.
///
/// I hate explicitly unwrapped optionals in Swift (or as I call them, "explosive optionals"). They
/// sidestep the responsibility of the dev to handle nil values, and they crash the app without
/// any specific information to send to a logger or debugger. If the nil state isn't a valid state,
/// and it necessitates a crash, I still want there to be a message handed off to the logger/debugger
