//  In the following, we describe:
//  
//     (1) The method which gets the path for the results ASCII files
//         from a "cna-configuration" file
//     (2) The codification for the names of the ASCII files
//     (3) The methods which writes the results in the ASCII files
//
//
//
// (1)-----------> Method to set the path for the results ASCII files
//
//      void  MyCnaRun->GetPathForResultsAsciiFiles(pathname);
//
//            TString pathname = name of a "cna-config" file located
//            in the user's HOME directory and containing one line which
//            specifies the path where must be written the .ascii result files.
//            (no slash at the end of the string)
//    
//   DEFAULT: 
//            void  MyCnaRun->GetPathForResultsAsciiFiles();
//            If there is no argument, the "cna-config" file must be named
//            "path_results_ascii.ecna" and must be located in the user's HOME
//            directory
//
//
// (2)-----------> Codification for the names of the ASCII files (examples):
//
//       aaa_nnnS_Rrrr_fff_ttt_SMnnn_pedestals.ascii   OR  aaa_nnnS_Rrrr_fff_ttt_Deennn_pedestals.ascii
//       aaa_nnnS_Rrrr_fff_ttt_SMnnn_HF_noise.ascii    OR  aaa_nnnS_Rrrr_fff_ttt_Deennn_HF_noise.ascii 
//       aaa_nnnS_Rrrr_fff_ttt_SMnnn_corss_cCCC.ascii  OR  aaa_nnnS_Rrrr_fff_ttt_Deennn_corss_cCCC.ascii 
//       etc...  
//
//  with:
//       aaa = Analysis name
//       rrr = Run number
//       fff = First requested event number
//       ttt = Number of requested events
//       CCC = Electronic Channel number in Stex
//       nnn = SM number or Dee number
//
//  Examples:
//       StdPed12_10S_R66689_1_50_SM1_pedestals.ascii
//       StdPed6_10S_R66689_1_50_Dee3_cor_ss_c2234.ascii
//
//
// (3)-----------> Methods which write the ASCII files:
//
//  The methods which write the ASCII files are the following:
//
//      void  WriteAsciiCovariancesBetweenSamples(Channel, MatrixSize, TMatrixD matrix);
//      void  WriteAsciiCorrelationsBetweenSamples(Channel, MatrixSize, TMatrixD matrix);
//      void  fT2dWriteAscii(code, px, py, MatrixSize, TMatrixD matrix) [private]
//      void  WriteAsciiHisto(CodeHisto, HistoSize, TVectorD histo)
//
//  Each of these methods corresponds to a "calculation method" of TEcnaRun.
//  The calculation method of TEcnaRun must have been been called before
//  using the writing method of TEcnaWrite.
