	BagSync.lua
		A item tracking addon similar to Bagnon_Forever (special thanks to Tuller).
		Works with practically any Bag mod available, Bagnon not required.

	NOTE: Parts of this mod were inspired by code from Bagnon_Forever by Tuller.

	This project was originally done a long time ago when I used the default blizzard bags.  I wanted something like what
	was available in Bagnon for tracking items, but I didn't want to use Bagnon.  So I decided to code one that works with
	pretty much any inventory addon.

	It was intended to be a beta addon as I never really uploaded it to a interface website.  Instead I used the
	SVN of wowace to work on it.  The last revision done on the old BagSync was r50203.11 (29 Sep 2007).
	Note: This addon has been completely rewritten.
