//              including CP violation effects
//
//Class to handle decays of the form SCALAR ->VECTOR PHOTON
//where the helicity amplitudes must be specified.  The
//first and third arguements are the magnetudes of the H+
//and H- helicity amplitudes respectively.  The second and
//fourth arguements are the phases.
//Calls EvtSVPHel.
