+//_____________________________________________________________
+// AliHLTTPCClustFinderNew
+//
+// The current cluster finder for HLT
+// (Based on STAR L3)
+//
+// The cluster finder is initialized with the Init function,
+// providing the slice and patch information to work on.
+// The input is a AliHLTTPCDigitRowData structure using the
+// Read function. The resulting space points will be in the
+// array given by the SetOutputArray function.
+//
+// There are several setters which control the behaviour:
+//
+// - SetXYError(Float_t): set fixed error in XY direction
+// - SetZError(Float_t): set fixed error in Z direction
+// (used if errors are not calculated)
+// - SetDeconv(Bool_t): switch on/off deconvolution
+// - SetThreshold(UInt_t): set charge threshold for cluster
+// - SetMatchWidth(UInt_t): set the match distance in
+// time for sequences to be merged
+// - SetSTDOutput(Bool_t): switch on/off output about found clusters
+// - SetCalcErr(Bool_t): switch on/off calculation of
+// space point errors (or widths in raw system)
+// - SetRawSP(Bool_t): switch on/off convertion to raw system
+//
+//
+// Example Usage:
+//
+// AliHLTTPCFileHandler *file = new AliHLTTPCFileHandler();
+// file->SetAliInput(digitfile); //give some input file
+// for(int slice=0; slice<=35; slice++){

+// cf->SetRawSP(kFALSE); //Convert space points to local system

+<pre>
+//_____________________________________________________________
+// AliHLTTPCFileHandler
+//
+// The HLT ROOT <-> binary files handling class
+//
+// This class provides the interface between AliROOT files,
+// and HLT binary files. It should be used for converting
+// TPC data stored in AliROOT format (outputfile from a simulation),
+// into the data format currently used by in the HLT framework.
+// This enables the possibility to always use the same data format,
+// whether you are using a binary file as an input, or a AliROOT file.
+//
+// For example on how to create binary files from a AliROOT simulation,
+// see example macro exa/Binary.C.
+//
+// For reading a AliROOT file into HLT format in memory, do the following:
+//
+// AliHLTTPCFileHandler file;
+// file.Init(slice,patch);
+// file.SetAliInput("galice.root");
+// AliHLTTPCDigitRowData *dataPt = (AliHLTTPCDigitRowData*)file.AliDigits2Memory(nrows,eventnr);
+//
+// All the data are then stored in memory and accessible via the pointer dataPt.
+// Accesing the data is then identical to the example 1) showed in AliHLTTPCMemHandler class.
+//
+// For converting the data back, and writing it to a new AliROOT file do:
+//
+// AliHLTTPCFileHandler file;
+// file.Init(slice,patch);
+// file.SetAliInput("galice.root");
+// file.Init(slice,patch,NumberOfRowsInPatch);
+// file.AliDigits2RootFile(dataPt,"new_galice.root");
+// file.CloseAliInput();

+//_____________________________________________________________
+// AliHLTTPCMemHandler
+//
+// The HLT Binary File handler
+//
+// This class does all the memory I/O handling of HLT binary files.
+//
+// Examples:
+// ---------
+//
+// 1) Reading a binary file:
+//
+// AliHLTTPCMemHandler file;
+// file.SetBinaryInput(filename);
+// file.Init(slice,patch);
+//
+// UInt_t nrowss;
+// AliHLTTPCDigitRowData *data = file.CompBinary2Memory(nrows);
+//
+// for(int i=0; i<nrows; i++)
+// {
+//
+// AliHLTTPCDigitData *dataPt = (AliHLTTPCDigitData*)data->fDigitData;
+// for(int j=0; j<data->fNDigit; j++)
+// {
+// pad = dataPt[j].fPad;
+// time = dataPt[j].fTime;
+// charge = dataPt[j].fCharge;
+// }
+//
+// file.UpdateRowPointer(data);
+//
+// }
+// file.CloseBinaryInput();
+// ________________________
+//
+// 2) Writing a binary file:
+//
+// //First of all you need to store the data in memory,
+// //and have a pointer to it of type AliHLTTPCDigitRowData.
+// //E.g. if you just want to write the data you read in example 1)
+// //into a new file, you can do the following:
+//
+// AliHLTTPCMemHandler newfile;
+// newfile.Init(slice,patch);
+// newfile.SetBinaryOutput(newfilename);
+// newfile.Memory2CompBinary((UInt_t)NumberOfRowsInPatch,(AliHLTTPCDigitRowData*)data);
+// newfile.CloseBinaryOutput();
+//
+//
+// Compressed file format:
+// -----------------------
+//
+// The data is RLE encoded and currently using _10_ bit range for the ADC-values.
+</pre>
