	This is an addon for World of Warcraft that adds statistical history to the auction data that is collected
	when the auction is scanned, so that you can easily determine what price
	you will be able to sell an item for at auction or at a vendor whenever you
	mouse-over an item in the game

	  (deprecated) libName: a module name (correct case or lowercase) - only this lib will be returned (not a list)
		should use AucAdvanced.GetModule(libType, libName, having) instead

	  moduleList is a table containing a list of moduleLibs matching the specified parameters
		in a specific order: sorted by libType-descending then lowerName-ascending (unless key mode was specified)
		if no modules matching the parameters are found the table will be empty (or unchanged if useTable was supplied)
