[erlang-questions] Request feedback on example project

[zxq9]

Two days ago I wrote a simple UUID utility as an example of bit syntax.
Yesterday I decided I wanted it to be an example of documentation and
readability as well.

I would like feedback from new and old Erlangers in terms of readability,
documentation, what is easy to understand, what is hard to understand, etc.
My goal is to develop a style plain enough that a utility application just
above the threshold of clear triviality (like a UUID utility) is mostly
understandable even to someone new to Erlang.

No ninja tricks should be in there. If there are any please bring them to
my attention so they can be removed.

Thanks
