 *  This module randomly generates decays along the particle trajectory length 
 *  according to actual particle decay length, taking into account for the boost

 *
 *  This module is to to be used after a PropagateParticle step or a similar module
 *  that calculates and store a trajectory length.
 *
 *  Particles that decay are not added to the OutputArray.
