// Class IceF2k
// Conversion of Amanda F2K data into IceEvent physics event structures.
// 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 F2K 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 F2K data using the Ralice/IcePack analysis tools. 
//
// Usage example :
// ---------------
//
// Note : This example creates automatically the ROOT output file, which
//        is the most user friendly way of running the conversion job. 
//        In the subdirectory /macros the example macro icef2k.cc provides
//        an example of how to create a ROOT output file yourself and passing
//        this file via a pointer to IceF2k. 
//
// gSystem->Load("ralice");
// gSystem->Load("icepack");
// gSystem->Load("iceconvert");
//
// IceF2k q("IceF2k","F2K 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);
//
// // Split level for the output structures
// q.SetSplitLevel(2);
//
// // Buffer size for the output structures
// q.SetBufferSize(32000);
//
// // The F2K input filename(s)
// q.AddInputFile("run7825.f2k");
//
// // 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();
//
// // Select various objects to be added to the output file
//
// TFile* ofile=q.GetOutputFile();
// 
// if (ofile)
// {
//  ofile->cd(); // Switch to the output file directory
//
//  AliObjMatrix* omdb=q.GetOMdbase();
//  if (omdb) omdb->Write();
//
//  AliDevice* fitdefs=q.GetFitdefs();
//  if (fitdefs) fitdefs->Write();
//
//  TDatabasePDG* pdg=q.GetPDG();
//  if (pdg) pdg->Write();
//
//  // Flush additional objects to the output file.
//  // The output file is not explicitly closed here
//  // to allow interactive investigation of the data tree
//  // when this macro is run in an interactive ROOT/CINT session.
