//
// Description:
//   Creates tracks with reps of type T inside them (makeTrack()), or swaps
//   in a T rep for the existing Rep (changeFit()).  In neither case
//   is a fit performed.  T reps have an option of allowing hit-dropping
//   and ambiguity-flipping while fitting; these can be turned on
//   by invoking setFlipAndDrop() for that track.
//
// Environment:
//      Software developed for the BaBar Detector at the SLAC B-Factory.
//
// Author(s): Gerhard Raven
