//
// This program performs a simulation of the mirrors (in detail all processes up
// to the camera front window.
//
// It is meaned only for test purposes of the mirror simulation. At the moment it
// is a copy of the normal ceres simulation (revision 18447), with all processor removed behind
// MSimAbsorption absapd (so the absorption by the pde of the SiPMs).
//
// It doesn't provide any graphical output, and the only output is a ASCII file
// with the information of the photons.
