// MMcEvtBasic
//
// This class contains the most basic MonteCarlo information
// with which an event has been generated
//
// Note: The azimuth fTelescopePhi angle in this and other MC classes 
// follow the convention in the Corsika program (see Corsika manual and
// TDAS 02-11). 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.
