        // This controller is intentionally written in a very verbose style. You will
        // notice:
        //
        // 1. Every 'if' statement has a matching 'else' (exception: simple error
        //    checks for a client API call)
        // 2. Things that may seem obvious are commented explicitly
        //
        // We call this style 'space shuttle style'. Space shuttle style is meant to
        // ensure that every branch and condition is considered and accounted for -
        // the same way code is written at NASA for applications like the space
        // shuttle.
