[Red5] UUIDs in ActionScript

[Art Clarke]

Thanks everyone -- a lot of great suggestions.  It does appear there is a
Flex version that would meet my needs, but I'm not using Flex, and don't
want to import those libraries.

Also, although I'd love to have version-1 UUIDs (those are the UUIDs that
are guaranteed to be unique in time and space based on things like MAC
addresseses), it's a nice to have right now.

So I went ahead and implemented a very basic UUID class for ActionScript
3.0.  It's version 4, and only as good as Flash's Math.random() function,
but it works well enough for my message-ids.

If anyone is interested, feel free to use.  It's under the MIT License:

In future versions I may implement some way to seed with a unique
space-seed, so some of the call-back mechanisms people brought up could be
made to work.  We'll see.

Flex has the UIDUtil class: http://livedocs.adobe.com/flex/2/langref/
