#	Locking switch prototype that uses just event
#	utility nodes.
#
#	Three EventUtility nodes are used (BooleanToggle, BooleanFilter,
#	and IntegerTrigger (twice)) to implement the locking switch.
#	The BooleanToggle node only reacts on an incoming TRUE event.
#	Then it negates it's internal value and sends it to BooleanFilter.
#	BooleanFilter separates TRUE and FALSE events so the correct
#	'whichChoice' can be sent as an output event.
