1. Evaluated cross section data for natural composition of elements 
for neutrons, protons, deuterons, tritons, He3, alpha, gamma

-- elZ   - elastic 
-- inelZ - inelastic
-- capZ  - capture

Data for selected isotopes below 20 MeV

-- inelZ_A - inelastic
-- capZ_A  - capture

Data format is G4VPhysicsVector compatible

These data are used by neutron cross section classes G4NeutronCaptureXS,
G4NeutronElasticXS, G4NeutronInelasticXS, and G4ParticleIvelasticXS.

2. Extra directory "neutrino" consists of files for x- and Q2- sampling 
of neutrino interactions with nucleon (nucleus). The sampling depends on 
the neutrino flavour, so a tree of directories will be implemented. 
The values of x and Q2 are used for the creation of the neutrino-nucleus 
interaction final state.
