	batteries for lua

	if required as the "entire library" (ie by this file), puts everything into
	global namespace by default as it'll presumably be commonly used

	if not, several of the modules work as normal lua modules and return a table
	for local-friendly use

	the others that modify some global table can be talked into behaving as normal
	lua modules as well by setting appropriate globals prior to inclusion

	you can avoid modifying any global namespace by setting

		BATTERIES_NO_GLOBALS = true

	before requiring, then everything can be accessed as eg

		batteries.table.stable_sort
