--[[ 	
	Still photography toggler script
	Version 1.6 (should work on all ML enabled cameras with the Lua module)
	Garry George June 2016
	http://photography.grayheron.net/
	Toggler script for ML settings.
	Toggle through ML settings using the selected option, ie a button you rarely use.
	Must be in LV.
