Here's a first release for the hair script.  All of the features seem to be working, but there are probably things which need to be improved.  I've done a quick test with the Sydney scalp prop.  The process works, but it seems like it will require a learning curve to determine how best to set up groups for the hair and position the path for the various features.

One problem I do note is that the "Y locks" aren't being defined very effectively on a more complex prop like the Sydney scalp prop.  The shaping propcess works fine for the locks, but they're broken up into smaller pieces than I'd like, making them hard to use for selection.

You should be able to run this on any grouped object.  It should grow the guidehairs for you if they don't already exist.  Then start adding markers to the scene and you're ready to start shaping the hair using the marker path.

I'll be working on trying to improve things for a bit yet, so if anyone finds a bug or problem, please let me know so I can try to fix it.
