//  Documentation:
//    An adjoint CS matrix is used by the model of a reverse process to sample an adjoint secondary (being equivalent to a forward primary). 
//    It represents the integration over the energy of the adjoint secondary (therefore the forward primary) of the differential cross section 
//    of the equiavlent forward  discrete process (Ionisation, Brem, PE effect, Compton,..) . Each reverse model has its own cross section matrix for a given cut, 
//    material couple. It is therefore recompute after a modification  of the cuts by the user.
