// Class description:
//
// Implements a trajectory point filter which accepts all points submitted to it.
//
// IMPORTANT: The base class heap allocates vectors of auxiliary
// points, which it does not delete. The vectors must find their way
// to a subclass of G4VTrajectoryPoint, which must take responsibility
// for deleting them.
