// Class IceRawTWR
// Conversion of Amanda raw TWR data into IceEvent data structures.
// The code to actually read the TWR raw data structures is an Ralice/IcePack
// implementation of Wolfgang Wagner's (Dortmund University, Germany)
// original read_twr_binary_file.cxx and wf2hit_new.cxx source code.
// The trigger information as encountered in the raw data, is available
// in the IceEvent structure via a device named "Trigger".
// The various triggers (and times) have been stored as different "hits"
// in this "Trigger" device, just like it was done in the IceF2k processor
// for the mu-daq F2K data.
// An indication of the active DAQ system is available in the IceEvent structure
// via a device named "Daq". Here the various daq systems (TWR, Muon, ...)
// from which the actual hits (ADC, LE, TOT) eventually will be composed
// are indicated as "signals" of the device itself. 
// This class is derived from AliJob providing a task-based processing
// structure on an event-by-event basis.
// The main object in the job environment is an IceEvent* pointer.
// In case the user has provided sub-tasks, these will be executed
// on an event-by-event basis after the IceEvent structure has been filled
// with the raw TWR data and before the final structures are written out.
// Note that the data structures are only written out if an outputfile has
// been specified via the SetOutputFile memberfunction.
// In case no outputfile has been specified, this class provides a facility
// to investigate/analyse raw TWR data using the Ralice/IcePack analysis tools.
//
// Usage example :
// ---------------
//
// gSystem->Load("ralice");
// gSystem->Load("icepack");
// gSystem->Load("iceconvert");
//
// IceRawTWR q("IceRawTWR","TWR raw data to IcePack data structure conversion");
//
// // Limit the number of entries for testing
// q.SetMaxEvents(10);
//
// // Print frequency to produce a short summary print every printfreq events
// q.SetPrintFreq(1);
//
// // The TWR raw data input filename(s)
// q.AddInputFile("twr_2005_101_009225_0983_57784_57850.dat.twr.to_tape_1");
//
// // Output file for the event structures
// q.SetOutputFile("events.root");
//
// ///////////////////////////////////////////////////////////////////
// // Here the user can specify his/her sub-tasks to be executed
// // on an event-by-event basis after the IceEvent structure
// // has been filled and before the data is written out.
// // Sub-tasks (i.e. a user classes derived from TTask) are entered
// // as follows :
// //
// //    MyXtalk task1("task1","Cross talk correction");
// //    MyClean task2("task2","Hit cleaning");
// //    q.Add(&task1);
// //    q.Add(&task2);
// //
// // The sub-tasks will be executed in the order as they are entered.
// ///////////////////////////////////////////////////////////////////
//
// // Perform the conversion and execute subtasks (if any)
// // on an event-by-event basis
// q.ExecuteJob();
