/*
 * Uuid
 *
 * UUIDs are unique numbers that are used for identifying individual units,
 * functions, programmes, or whatever you want to tag.
 *
 * In this demo, press the Arduino Reset button to generate a new number.
 *
 * UUIDs can be assigned sequentially from allocated blocks of numbers, but
 * they are most powerful when randomly assigned. UUIDs are such big numbers
 * that, for all effective purposes, no two numbers will ever match.
 *
 * UUIDs are particularly useful in web-aware devices, or radio networks.
 *
 * For a discussion of the use of UUIDs, see
 *   http://en.wikipedia.org/wiki/Universally_Unique_Identifier
 *
 * For implementation details of UUIDs, see
 *   http://tools.ietf.org/html/rfc4122
