// Class Description:
|
|
// This class represents the partilce under tracking.
|
|
// It includes information related to tracking for examples:
|
|
// 1) current position/time of the particle,
|
|
// 2) static particle information,
|
|
// 3) the pointer to the physical volume where currently
|
|
// the particle exists
