//==========
// MRawEvt 
//    
// One Event is a sample of FADC measurements of different Pixels 
// (Photomultipliers) from the Camera of MAGIC. So all data (FADC) of the 
// interesting pixels are the modules of an event. To describe pixels the 
// class MRawPixel is used and the class MRawCrate to describe Crates.
// To define a single events some other data members are needed 
// (Time of the events, tirgger pattern of event..)
// 
// To describe one event on the level of FADC values the Class MRawEvt is
// created. It has the following data members: 
//
// ----------
//
// UInt_t    DAQEvtNumber    
//
// This it the number of the Event in one 
// data run. The first event in this run get
// the number zero. The next one is one bigger.
//
// Assuming that one run takes 1 hour and a
// triggerrate of 1kHz the number must be able
// to reach 3.6e6 Events. To reach this number
// you need at least 22 bits. This is the reason
// why we use an integer (of root type UInt_t)
// with a range to 4.2e9. 
//
// ----------
//
// UInt_t   AbsTime[2]
//   
// Time of the event. 
// The start point of the time determination can be
// the millenium. From that start point the time is
// measured in 200ns-count. One day for example
// contains 432.e9 counts. An array of two unsigned Int is able to 
// contain 1.8e19 200ns-counts. This corresponds to 41.e6
// days. This should be more than the livetime of MAGIC.
//
// ----------
//
// UInt_t  FstLvlTrigNumber
//
// Number of first level trigger
// This member counts the number of First Level Trigger
// between the last and this event. May be that due to 
// dead time of the DAQ this number is different from 1.
// If the DAQ is fast enough, this value should be 1. 
// This may be usefull in GammaRayBursts and if we 
// apply a data reduction in the DAQ-chain, which selects
// only good events. 
//
// ----------
//
// UInt_t  SecLvlTrigNumber
//
// Number of second level trigger
// This member counts the number of Second Level Trigger
// between the last and this event. 
//
// ----------
//
// UInt_t  TriggerPattern[2]
//
// Trigger Pattern used for this event
// Each event triggers for a particular configuration and each  
// configuration shoul have an ID (which is not fixed yet).
//
// ----------
//
// Byte_t   TriggerType 
//
// Type of Trigger. 
// This is a Byte (8 bit) to indicated the status of 
// the event (Normal (0), Pedestal (1), Calibration (2), etc). 
//
// ----------
//
// Byte_t   AllLowGainOn
//
// Type of Trigger. 
// This is a Byte (8 bit) to indicated if any of the pixels 
// have a non-negligible low gain (1) or not (0) 
//
// ----------
//
// TClonesArray  *Crates
//
// Array of Crates
// The Clones array is a list of the Crates used in one
// event with the information about the Crate. 
//
// ----------
//
// TClonesArray  *PixelsHigh
//
// Array of Pixels for their high voltage channel
// The Clones array is a list of the Pixels used in one
// event with the information about the Pixels. 
//
//
// ----------
//
// TClonesArray  *PixelsLow
//
// Array of Pixels for their low voltage channel
// The Clones array is a list of the Pixels used in one
// event that have a significant signal in the low gain channel
// with the information about the Pixels. 
//
//
