//
// MMcConfigRunHeader
//
// Root storage container for the MONTE CARLO CONFIGURATION information
//
// It saves in a root file all the infromation about values in the
// configuration files used in the Monte Carlo production: MagicDef
// (definition of the teslescope), Reflectivity.dat (mirror reflectivities),
// qe.dat (PMT QEs), axisdev.dat (mirrors deviations) and lightguides.dat
// (Effect of the Light Guides).
//
//
// Class Version 2:
// ----------------
// removed obsolete variables which are no longer used by reflector, 
// nor present in the magic.def file:  fFocalStdev, fPointStdev, fDevAdjust
//
// Class Version 3:
// ----------------
// Added member fLightCollectionFactorOuter so that we can store
// the data on the simulatedlight collection efficiency (light
// guides + plexiglas +...) as a function of incidence angle for
// outer and inner pixels independently.
//
// Class Version 4:
// ----------------
// Added member fMirrorFraction, the "active" fraction of the
// mirror dish, to account for reflectivity losses, missing
// mirrors, etc.
//
// Class Version 5:
// ----------------
// Added member fPmtTimeJitter, the time jitter of the PMTs (sigma
// of gaussian) for each photoelectron.
//
// Class Version 6:
// ----------------
// Added fParaboloidFocal
