//      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. 
//
