//////////////////////////////////////////////////////////////////////////////////
//
// class MMcConfigRunHeader
//
// Authors: O. Blanch, A. Moralejo 
//
// Container to keep some data on the used MC simulation parameters
// 
// 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.
//
// Version 4: Added member fMirrorFraction, the "active" fraction of the 
//            mirror dish, to account for reflectivity losses, missing 
//            mirrors, etc.
//
// Version 5: Added member fPmtTimeJitter, the time jitter of the PMTs
//            (sigma of gaussian) for each photoelectron.
