UUID

A custom UUID implementation (not to be confused with java.util.UUID or RFC4122 implementations) that allows natural sorting by timestamp based on the string or numeric representation.

The UUID consists of 16 bytes (128 bits) broken up into 2 longs:

timeAndCounter: {6-Byte Millis since epoch}{2-Byte Counter} nodeIdAndRandom: {2-Byte Node ID}{6-Byte Random Number}

The "pretty" hex encoded representation is: {6-byte millis since epoch}-{2-byte-counter}-{2-byte-optional-node-id}-{4-byte-random}

Example: 015247f01787-9740-85e0-3e9672a8dfa2
