Four Input Exclusive-Or Gate
This circuit implements a Boolean logic function
with four inputs and one output, where the output will only be "true"
if only one of the four inputs is "true."
This function is useful for designs in which the
activation of one condition inhibits the ability to
activate the second, third, or fourth condition at the same time.
