This model tests the implementation of IDEAS.Utilities.Math.IntegratorWithReset with and without reset, and with different start values and reset values.
The integrator intWitRes1 is triggered by a sample
trigger which becomes true at t=0, while
intWitRes2 is triggered by a boolean pulse with is
true at t=0. Hence, intWitRes1 starts with
y(0)=y_reset while intWitRes2 starts with
y(0)=y_start.
