Exclusive OR function block XORQT

The exclusive OR function (XORQT) function is used to generate combinatory
expressions with boolean variables. XORQT function has two inputs and two outputs.
One of the outputs is inverted. The output signal OUT is 1 if the input signals are
different and 0 if they are equal.
