0031 // Class description:
0032 //
0033 // Defines the primary generator action used for tracing magnetic
0034 // field lines.
0035 // It generates the primary vertex by using the user defined primary
0036 // generator action and replaces only the definition of the particle
0037 // to be tracked by a "charged-geantino".
0038 // The user can define start position for field line tracking in
0039 // his/her own primary generator action.
