// File: hitfit/Fit_Result_Vec.h
// Purpose: Hold a set of Fit_Result structures.
// Created: Jul, 2000, sss, based on run 1 mass analysis code.
//
// This class holds pointers to a set of Fit_Result's, resulting from
// different jet permutation with some consistent selection.
// The results are ordered by increasing chisq values.  A maximum
// length for the vector may be specified; when new results are added,
// those with the largest chisq fall off the end.
//
// The Fit_Result objects are reference counted, in order to allow them
// to be entered in multiple vectors.
