An implementation of Universal Unique Identifier (UUID). See [http://tools.ietf.org/html/rfc4122](http://tools.ietf.org/html/rfc4122)
The current implementation supports only a JVM backend due to dependencies upon [[java.security::MessageDigest]],
to produce random bytes, and to implement MD5/SHA-1 hashing, respectively.
According to the standard, the following components make up a [[UUID]] :
- timeLow (8 digits)
- timeMid (4 digits)
- timeHiVersion (4 digits)
- clockSeqHiVariant (2 ...
