//-------------------------------------------------------------------------------------------------------------------------------------------------------
//
//   FEventViewer.c      version 1.03  (2006-04-04)
//
//   Shows PAMELA events - Emiliano Mocchiutti
//
//-------------------------------------------------------------------------------------------------------------------------------------------------------
//
//
//   Standard use:
//
//   bash> EventViewer
//
//   For further informations use:
//
//   EventViewer --help
//
//   or
//
//   EventViewer --version
//  
//-------------------------------------------------------------------------------------------------------------------------------------------------------
//
//   Changelog:
//
//   1.02 - 1.03 (2006-04-04): Make it possible to select events with the calorimeter also when generating level1 from level0.
//
//   1.01 - 1.02 (2006-03-22): Read calorimeter ADC2MIP flight conversion file. Do not install FEventviewer.cxx!
//
//   1.00 - 1.01 (2006-03-09): Flight version, read unique YODA file. Many capabilities disabled at the moment (reads only LEVEL0 data).
//
//   0.00 - 1.00 (2006-03-09): Clone of EventViewer.c v9r01.

25			//
26			// 1.02 - 1.03 (2006-04-04): Make it possible to select events with the calorimeter also when generating level1 from level0.
27			//
28			// 1.01 - 1.02 (2006-03-22): Read calorimeter ADC2MIP flight conversion file. Do not install FEventviewer.cxx!
29			//
30			// 1.00 - 1.01 (2006-03-09): Flight version, read unique YODA file. Many capabilities disabled at the moment (reads only LEVEL0 data).
31			//
32			// 0.00 - 1.00 (2006-03-09): Clone of EventViewer.c v9r01.
