-<pre>
-//_____________________________________________________________
-// 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.
