The UUID Library is a library for generating
UUIDs (Universally Unique IDentifiers), which
are also known as GUIDs (Globally Unique IDentifiers).
It currently only supports generating Variant 1, Type 4 UUIDs, which
are random bit strings (these are the UUIDs generated by the
function on Microsoft Windows).
The UUID Library was first included in Version 110.97 of SML/NJ.
