//*-* The following structure members are set to 1 if the option is selected:
int Quiet; // "Q" Quiet mode. No print
int Verbose; // "V" Verbose mode. Print results after each iteration
int Bound; // "B" When using pre-defined functions user parameter settings are used instead of default one
int Chi2; // "X" For fitting THnsparse use chi2 method (default is likelihood)
int Like; // "L" Use Log Likelihood. Default is chisquare method except fitting THnsparse
int User; // "U" Use a User specified fitting algorithm (via SetFCN)
int W1; // "W" Set all the weights to 1. Ignore error bars
int Errors; // "E" Performs a better error evaluation, calling HESSE and MINOS
int More; // "M" Improve fit results.
int Range; // "R" Use the range stored in function
int Gradient; // "G" Option to compute derivatives analytically
int Nostore; // "N" If set, do not store the function graph
int Nograph; // "0" If set, do not display the function graph
int Plus; // "+" Add new function (default is replace)
int Integral; // "I" Use function integral instead of function in center of bin
int Nochisq; // "C" In case of linear fitting, don't calculate the chisquare
int Minuit; // "F" If fitting a polN, switch to minuit fitter
int NoErrX; // "EX0" or "T" When fitting a TGraphErrors do not consider error in coordinates
int Robust; // "ROB" or "H": For a TGraph use robust fitting
int StoreResult; // "S": Stores the result in a TFitResult structure
double hRobust; // value of h parameter used in robust fitting
