//  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 equivalent 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 recomputed after a modification of the cuts by the user.
