 read next data record (if any)

 read next constraint record (if any)

 assign weight

 assign run

 assing derivs of loc.eq.

 write data of single measurement. Note: the records ignore regrouping, store direct parameters

 Define a constraint equation.

 Define a constraint equation.

    Perform local parameters fit once all the local equations have been set
    -----------------------------------------------------------
    localParams = (if !=0) will contain the fitted track parameters and
    related errors

 performs a requested number of global iterations

 perform global parameters fit once all the local equations have been fitted

 solve global matrix equation MatCGlob*X=VecBGlo and store the result in the VecBGlo


  printf("GlobalMatrix\n");
  fMatCGlo->Print("l");
  printf("RHS\n");
  for (int i=0;i<fNGloPar;i++) printf("%d %+e\n",i,fVecBGlo[i]);

 return the limit in chi^2/nd for n sigmas stdev authorized
 Only n=1, 2, and 3 are expected in input

 Number of iterations is calculated from lChi2CutFac

 return error for parameter iPar

 return pull for parameter iPar

  Print the final results into the logfile

 validate record according run lists set by the user

 set the list of runs to be rejected

 set the list of runs to be selected

 initialize parameters, account for eventual grouping

 initialize sigmas, account for eventual grouping
