This library generates Universally Unique IDs (UUIDs/GUIDs)
as per RFC4122.

Version 1 UUIDs are pretty much guaranteed to be unique as
they are tied to the time and place of creation.

Version 4 UUIDs have a very high probability of being unique,
and do not leak identifiable information.

Version 5 UUIDs are generated for a name in a namespace and
that name and namespace combination will be the same every
time it is generated. A v5 UUID has a very high probability
of being unique within a namespace.

Unlike utility.library's GetUniqueID() function, IDs
generated by uuid.library will be unique across reboots.
However they are not 32-bit values so do not fit the same
use case.

A command line tool is provided to generate UUIDs.
It generates v1 UUIDs by default.


Generate a v4 UUID:
1.> uuid ver 4

Generate a v5 UUID using the previous v4 UUID as a namespace:
1.> uuid ver 5 b1acd74e-7af4-4a6b-afcc-676466aa1231 uuid.library

Copy C to C:, Libs to Libs:, and
SDK into the SDK if you have it installed.
