/**
 * Generates a new UUID and passes it to the given callback function.
 *
 * Uses the a command-line uuid generator. Caches UUIDs to avoid
 * unneccessary spawning of new processes.
 *
 * You can easily adjust the script used to create the UUID. By
 * default I am using the OSSP uuid program, which is available in
 * most linux distro's package managers (e.g. `sudo apt-get install
 * uuid` on ubuntu).
