// Module: EvtGen/EvtSSDCP.hh
//
// Description: This module is part of the unification of simulation of CP violation in
//              B decays. This model handles decays of the type B->SD where D is either
//              a spin 0, 1, or 2 particle. See long writeup for more information.
//
// Modification history:
//
//    DJL/RYD     August 12, 2001         Module created
