// Purpose: This file contains the class definition for PulseSeries.
// PulseSeries is a concrete class. A PulseSeries object provides
// a pulse time series. The factor is given by the pseudoTime (t),
// pulse period (T), pulse width (pw) and phase shift (phi),
// and a constant factor provided in the constructor,
// the duration by tStart and tFinal;
//
// What: "@(#) PulseSeries.h, revA"
