// MJOptimize
//
// Class for otimizing the parameters of the supercuts
//
// Minimization Control
// ====================
//
//   To choose the minimization algorithm use:
//         void SetOptimizer(Optimizer_t o);
//
//   Allowed options are:
//        enum Optimizer_t
//        {
//            kMigrad,      // Minimize by the method of Migrad
//            kSimplex,     // Minimize by the method of Simplex
//            kMinimize,    // Migrad + Simplex (if Migrad fails)
//            kMinos,       // Minos error determination
//            kImprove,     // Local minimum search
//            kSeek,        // Minimize by the method of Monte Carlo
//            kNone         // Skip optimization
//        };
//
//   For more details on the methods see TMinuit.
//
//
//   You can change the behaviour of the minimization using
//
//        void SetNumMaxCalls(UInt_t num=0);
//        void SetTolerance(Float_t tol=0);
//
//   While NumMaxCalls is the first, Tolerance the second arguement.
//   For more details start root and type
//
//        gMinuit->mnhelp("command")
//
//   while command can be
//        * MIGRAD
//        * SIMPLEX
//        * MINIMIZE
//        * MINOS
//        * IMPROVE
//        * SEEK
//
//   The default (num==0 and tol==0) should always give you the
//   corresponding defaults used in Minuit.
//
//
// FIXME: Implement changing cut in hadronness...
// FIXME: Show MHSignificance on MStatusDisplay during filling...
// FIXME: Choose step-size percentage as static data membewr
// FIXME: Choose minimization method
