//
//  This class describes a sequence. For sequences see:
//    http://magic.astro.uni-wuerzburg.de/mars/db/queryseq.html
//
//  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:
//
// ===========================================================================
//
//  sequence.txt
//  ------------
//
//   # Sequence number (identifier)
//   Sequence:     31015
//   # Observation Period (used to get the path-names)
//   Period:       18
//   # Date of sunrise of the observation night
//   Night:        2004-06-24
//
//   # Start time of the sequence (first data run)
//   Start:        2004-06-24 03:12:42
//   # Run number of last data run in sequence
//   LastRun:      31032
//   # Project name of data-runs of sequence
//   Project:      3EG2033+41
//   # Source name of all runs of sequence
//   Source:       3EG2033+41
//   # Trigger table of data-runs of sequence
//   TriggerTable: L1_4NN:L2_DEFAULT
//   # HV Setting table of data-runs of sequence
//   HvSettings:   HVSettings_FF36q
//   # Total number of data-events in sequence
//   NumEvents:    250914
//
//   # List of all runs of this sequence
//   Runs: 31015 31016 31017 31018 31019 31020 31021 31022 31023 31024 31025 31026 31027 31028 31029 31030 31031 31032
//
//   # List of all calibration runs of this sequence
//   CalRuns: 31015 31016 31017
//   # List of pedestal runs belonging to the calibration runs of this sequence
//   PedRuns: 31018
//   # List of all data runs belonging to this sequence
//   DatRuns: 31019 31020 31022 31023 31024 31025 31027 31028 31030 31032
//
//   # List of run types of all runs
//   31015: C
//   31016: C
//   31017: C
//   31018: P
//   31019: D
//   31020: D
//   31021: P
//   31022: D
//   31023: D
//   31024: D
//   31025: D
//   31026: P
//   31027: D
//   31028: D
//   31029: P
//   31030: D
//   31031: P
//   31032: D
//
// ===========================================================================
//
//  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]");
