0034 // Class description:
0035 //
0036 // Defines the primary generator action used for tracing magnetic
0037 // field lines.
0038 // It generates the primary vertex by using the user defined primary
0039 // generator action and replaces only the definition of the particle
0040 // to be tracked by a "charged-geantino".
0041 // The user can define start position for field line tracking in
0042 // his/her own primary generator action.
