Frame_MainFrame.lua
Authors: mrmr
Version: 1.04.2
------------------------------------------------------
Description: 
    	Main Frame Object
    1.00
		-- Initial Ace2 release
	1.99a
		-- Ally addition starter version
    1.03
		-- No Changes. Just adjusting "version".
    		1.99x for a beta release was a weird choise.
	1.04.1
		-- Main Frame object
	1.04.2
		-- Reworked "MetaMapBWP" and renamed to "MetaMap"
			cause now there's support for MetaMapNotes too
			Now, the methods are called:
		obj.RefreshMetaMap()
		obj.SetMetaMapDestination(self, nX, nY, sZone, title, step, label, mode)
			Diffentes modes, produces different behaviour, 
			see the source for insight
