EmacsLisp interface to UUIDs.
There are only 2 functions that are useful for general Elisp programming:
uuid-create
Create a new UUID object.
Using version 4 (random) because it's likely easiest to implement, plus it satisifies the privicy concerns of wackos.
uuid-to-stringy uuid
Convert uuid to a string
uuid-string
Make a string form of a UUID directly.
