/////////////////////////////////////////////////////////////////////////// 
// HMdcHitF is the reconstructor that transforms the calibrated      // 
// hits in one mdc module (HMdcCal3) in segments (HMdcHitAux).        // 
// It contains the parameter of the fit (maximum chi2 allowed, minimum   // 
// number of hits required in a segment...), a pointer to the calibrated // 
// data to be fitted, to the corresponding geometry, and the collection  // 
// of segments obtained from the fit.                                    // 
// It contains the following functions:                                  // 
//    - a default constructor: initializes  minNumHits = 4,  maxChi = 1, // 
//                             maxNumCommonHits = 3                      // 
//    - HMdcHitF(HMatrixCategory* data, HMdcModuleGeometry* mdcGeo):       // 
//           Constructor:                                                // 
//               - sets the minimum number of hits to 4                  // 
//               - sets the maximum chi2 to 1.                           // 
//               - mdcCal points to the data passed as argument, and the // 
//                 appropiate setup is done                              // 
//               - geo points to mdcGeo, the geometry passed as argument // 
//    - HMdcHitF(HCategory* data,HMdcModuleGeometry* mdcGeo,HCategory* seg)// 
//           Constructor:                                                // 
//               - sets the minimum number of hits to 4                  // 
//               - sets the maximum chi2 to 1.                           // 
//               - mdcCal points to the data passed as argument, and the // 
//                 appropiate setup is done                              // 
//               - geo points to mdcGeo, the geometry passed as argument // 
//               - mdcSegments points to seg, the segments category      // 
//    - a default destructor                                             // 
//    - setMinNumHits(Int_t min): sets minimum number of hits to min.      // 
//        If min < 4, sets minimum number of hits to 4, and an error     //  
//        message is printed                                             // 
//    - fit(HMdcCal3* listCal[6], Int_t listPlanes[6], Int_t numHits):  // 
//          General Least Squares fit to get slopes and intercepts in 2  // 
//          projections plus their variances. It is based on the FORTRAN // 
//          subroutine STFIT1.                                           // 
//          Fits the calibrated data of listCal and stores the result of //

//    - checkFit(HMdcHitAux* segment): Checks the fit: returns TRUE if  //  
//         * the number of hits in the segment is greater or equal than  // 
//           minNumHits.                                                 //

//         * the chi2 of the fit is not greater than maxChi.             // 
//    - find(Int_t listPlanes[6], Int_t nWantedHits, Int_t seg):               // 
//        Finds segments with hits belonging to the planes listed in the // 
//        nWantedHits first elements of listPlanes. The segments, once   // 
//        they pass several checks, are stored in the collection of      // 
//        segments, starting in the position given by seg.               // 
//        The basic procedure is the following:                          // 
//        * find hits in planes listPlanes[0] .. listPlanes[3].          // 
//        * calculate the parameters of the straight line defined by     // 
//          these hits                                                   // 
//        * looks for hits Int_t listPlanes[4] and/or listPlanes[5]        // 
//          (depending on nWantedHits), that are close to the            // 
//          intersection of that line with these planes.                 // 
//        * call the fit function with this collection of hits.          // 
//        * if the segment passes checkFit and checkCommon then it is    // 
//          added to the collection of segments in the position          // 
//          indicated by seg, and seg is incremented.                    // 
//     - markHits(Int_t first, Int_t last):  mark used-hits in segments      // 
//        in the positions between first and last in the collection of   // 
//        segments.                                                      // 
//     - checkCommon(HMdcHitAux* thissegment):  check if thissegment    // 
//         has common hits with other segments in the collection of      // 
//         segments. If some other segment (let's call it oldsegment) is // 
//         found with at least maxNumCommonHits in common with           // 
//         thissegment, then the chi-square of the segments are compared,// 
//         and the one with lower chi-square is keeped in the collection // 
//         of segments :                                                 // 
//            * if the lower chi-square belongs to thissegment, then     // 
//              oldsegment is marked to be deleted and then the function // 
//              returns FALSE. After that, in find function, thissegment // 
//              will be added to the collection of segments              // 
//            * if the lower chi-square corresponds to oldsegment, then  // 
//              the function returns TRUE, and thissegment will not be   // 
//              added to the collection of segments in the find function // 
//     - printSegments(ofstream& file): print information about the      // 
//         segments in the segments collection to file                   // 
//     - execute(void):finds combination of planes where to search for   // 
//         hits, and calls the function find with this combination.      // 
//     - plotResid (Int_t plane, Text_t* filename= "res1.root",            //
