// Description: Routine to decay scalar -> vector + photon
//              by specifying the helicity amplitudes
//
//Class to handle decays of the form SCALAR -> VECTOR PHOTON
//where the helicity amplitudes must be specified. The
//first and third arguments are the magnitudes of the H+
//and H- helicity amplitudes respectively. The second and
//fourth arguements are the phases.
//Calls EvtSVPHel.
