// Description: class TrkHotListUnowned.  A copy of TrkHotListFull where the
// hots are not owned by this class.  This is useful in nested reps like the
//  mini-rep, where only 1 can truely own the hots but both may need access to
// them.
//
// Environment:
//      Software developed for the BaBar Detector at the SLAC B-Factory.
