This model represents a third order Quantized State System integrator.
As inputs, it has to receive three messages: one with type == 1
and as value the value of the signal to integrate; one with type ==
2 and value equal to the first derivative of the signal and; the
last with type == 3 and the value of the second derivative of the
signal.
It generates three output messages: one with type == 1 and the
value of the integrated signal; one with type == 2 and the value of
the first derivative of the integrated signal and; one with type ==
3 and the value of the second derivative of the integrated
signal..
The quantum parameter represents the threshold to detect
changes in the input signal.
The startX parameter represents a guess for the initial
value of the input signal.
