//
//  This class describes a sequence. For sequences see:
//    http://db.astro.uni-wuerzburg.de
//
//  A sequence is a collection of runs which should be used together.
//  Any run can be contained only once.
//
//  Here is an example how a file describing a sequence could look like.
//
//  Reading the file is based on TEnv. For more details see also
//  the class reference of TEnv.
//
// ===========================================================================
//
//  sequence.txt
//  ------------
//
//   # Sequence number (identifier) - necessary if the path
//   # contains the sequence number, e.g. image files
//   Sequence:     31015
//
//   # Observation Period (not needed)
//   Period:       18
//
//   # Date of sunrise of the observation night - necessary if the path
//   # contains the date, e.g. raw data
//   Night:        2004-06-24
//
//   # Start time of the sequence (first data run, not needed)
//   Start:        2004-06-24 03:12:42
//
//   # Run number of last data run in sequence (not needed)
//   LastRun:      31032
//
//   # Project name of data-runs of sequence (not needed)
//   Project:      3EG2033+41
//
//   # Source name of all runs of sequence (not needed)
//   Source:       3EG2033+41
//
//   # Trigger table of data-runs of sequence (not needed)
//   TriggerTable: L1_4NN:L2_DEFAULT
//
//   # HV Setting table of data-runs of sequence (not needed)
//   HvSettings:   HVSettings_FF36q
//
//   # Total number of data-events in sequence (not needed)
//   NumEvents:    250914
//
//   # Whether this is MC data or not (necessary in case of MCs if
//   # default paths should be used)
//   MonteCarlo: Yes
//
//   # List of all runs of this sequence (not needed)

//
//   # List of all calibration runs of this sequence (necessary if accessed)
//   CalRuns: 31015 31016 31017
//   # List of pedestal runs belonging to the calibration runs of this sequence (necessary if accessed)
//   PedRuns: 31018
//   # List of all data runs belonging to this sequence (necessary)
//   DatRuns: 31019 31020 31022 31023 31024 31025 31027 31028 31030 31032
//
//   # Just for fun ;-) (not needed, but helpful)
//   Comment: This is a template for a sequence file
//
// ===========================================================================
//
//  For special cases you can also setup a sequence directly from a macro,
//  for example:
//
//    MDirIter pediter, datiter, caliter;
//
//    MSequence seq;
//    seq.SetNight("2004-07-06");
//    seq.AddPedRuns(31751);
//    seq.AddCalRuns(31752);
//    seq.AddDatRuns(31753, 31764);
//    seq.SetupPedRuns(pediter);
//    seq.SetupCalRuns(caliter);
//    seq.SetupDatRuns(datiter);
//
//  or
//
//    MDirIter iter;
//
//    MSequence seq;
//    seq.SetNight("2004-07-06");
//    seq.AddRuns(31753, 31764);
//    seq.SetupRuns(iter);
//    seq.SetupPedRuns(iter, "/mypath", "[DPC]");
//
