// Class to calculate calibration parameters  from beam tests etc.
//  First pass - one should calcuate pedestals, in the second pass - gains.
//
//     To calculate pedestals we scan pedestals events and fill histos for each
//     channel. Then in each histo we find maximum and fit it with Gaussian in the 
//     visinity of the maximum. Extracted mean and width of distribution are put into 
//     resulting histogram which cheks results for 'reasonability'.
//
//     To evaluate gains: scans beam events and calculate gain in the cristall with 
//     maximal energy deposition, assuming, that 90% of energy deposited in it. 
//     For each channel separate histogramm is filled. When scan is finished, 
//     these histograms are fitted with Gaussian and finds mean and width, which 
//     are put in final histogram. Finaly gains are checked for deviation from mean. 

//     Finally fills database.
//
// Use Case:
//       AliPHOSCalibrator * c = new AliPHOSCalibrator("path/galice.root") ;
//       c->AddRun("path2/galice.root") ; 
//       c->ScanPedestals();
//       c->CalculatePedestals();             
//       c->WritePedestals();
//       c->ScanGains() ;
//       c->CalculateGains() ;
//       c->WriteGains() ;
