This model tests the implementation of IBPSA.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.
