34 // Class Description:
35 // This class represents the Step of a particle tracked.
36 // It includes information of
37 // 1) List of Step points which compose the Step,
38 // 2) static information of particle which generated the
39 // Step,
40 // 3) trackID and parent particle ID of the Step,
41 // 4) termination condition of the Step,
