/**
 * @class AliHLTTPCMemHandler
 * The HLT Binary File handler 
 *
 * This class is the old memory I/O handler of HLT binary files.
 * Some functionality is still used in the current code, mainly
 * conversion of TPC digits into the format understandable by the
 * components.
 * <pre>
 *  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>
