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