//  Description:
//    This class represents the Step of a particle tracked.
//    It includes information of 
//      1) List of Step points which compose the Step,
//      2) static information of particle which generated the 
//         Step, 
//      3) trackID and parent particle ID of the Step,
//      4) termination condition of the Step,
