// File: hitfit/Lepjets_Event_Jet.h
// Purpose: Represent a `jet' in a Lepjets_Event.
// Created: Jul, 2000, sss, based on run 1 mass analysis code.
//
// This is like Lepjets_Event_Jet, except that we store some
// additional information:
//
//   - svx tag flag
//   - slt tag flag
//   -   slt lepton 4-vector
//   -   slt lepton energy deposition
