// File: hitfit/Fit_Results.h
// Purpose: Hold the results from kinematic fitting.
// Created: Jul, 2000, sss, based on run 1 mass analysis code.
//
// This is a set of lists of fit results.
// Each list corresponds to some subset of jet permutations:
//   all permutations, btagged permutations, etc.
