//
//  MMcEvt
//
// This class handles and contains the MonteCarlo information
// with which the events have been generated
// This information exists for each event.
//
// Note: All the azimuth Phi angles in this and other MC classes follow
// the convention in the Corsika program (see Corsika manual). There, phi
// is the azimuth of the momentum vector of particles, and is measured
// from the north direction, anticlockwise (i.e, west is phi=90 degrees).
// When it refers to the telescope orientation, it is the azimuth of a 
// vector along the telescope axis, going from the camera to the mirror. 
// So, fTelescopeTheta=90, fTelescopePhi = 0 means the telescope is 
// pointing horizontally towards South. For an explanation, see also 
// TDAS 02-11.
//
// Version 4: 
//   - Added member fFadcTimeJitter
//
// Version 5:
//   - removed fPartId, fEnergy, fImpact, fTelescopeTheta, fTelescopePhi
//   - derives now from MMcEvtBasic which contains all these values
//   - moved ParticleId_t to base class MMcEvtBasic
//
// Version 6:
//   - added fEventReuse
