//
// Description:
//   Creates tracks with HelixReps inside them (makeTrack()), or swaps 
//   in a HelixRep for the existing Rep (changeFit()).  In neither case 
//   is a fit performed.  HelixReps 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.
