//
//  MSimTrigger
//
// This task takes the pure analog channels and simulates a trigger
// electronics.
//
// In a first step several channels can be summed together by a look-up table
// fRouteAC.
//
// In a second step from these analog channels the output of a discriminator
// is calculated using a threshold and optional a fixed digital signal length.
//
// The signal length of the digital signal emitted by the discriminator
// can either be bound to the time the signal is above the threshold
// defined by fDiscriminatorThreshold if fDigitalSignalLength<0 or set to a
// fixed length (fDigitalSignalLength>0).
//
// With a second look-up table fCoincidenceMap the analog channels are
// checked for coincidences. The coincidence must at least be of the length
// defined by fCoincidenceTime. The earliest coincide is then stored as
// trigger position.
//
// If a minimum multiplicity m is given, m signals above threshold
// in the coincidence patterns are enough to emit a trigger signal.
//
//
// For MAGIC1:
//  - fDigitalSignalLength between 6ns and 12ns
//  - fCoincidenceTime between 0.25ns to 1ns
//
//
//  Input Containers:
//   IntendedPulsePos [MParameterD]
//   MAnalogChannels
//   MRawRunHeader
//
//  Output Containers:
//   TriggerPos [MParameterD]
//   MRawEvtHeader
