 - fixed typo in comments (no code change)

 - G4Element - always define effective number of nucleons as
     fNeff = fAeff/(g/mole) (address concern of J. Leacock:
     HyperNews/geant4/get/hadronprocess/1495.html); it is recommended
     to use element->GetN() for average atomic mass, for number of
     nucleons to use G4lrint(element->GetN())
 - G4IonisParamMat - use double argument to compute A^2/3
 
 22-10-15 V.Ivanchenko (materials-V10-01-09)

 - G4IonisParamMat - added protection on the new correction
     for the case of large diference between nominal density and
     defined density of the material; for big difference
     Sternheimer-1971 parameterisation is used, while normally
     Sternheimer-1984 is applied; important for vacuum and
     low-density gas
 
 11-08-15 V.Ivanchenko (materials-V10-01-06)

 - G4Material, G4NistManager, G4NistMaterialBuilder, G4IonisParamMat
     introduced NTP_Temperature=20C; set this tempature default for
     all materials instead of STP_Temperature; this is needed,
     because NIST materials are defined for NTP and not for STP
     conditions; addressed problem report #1704; no change in
     results of EM testing suite (densities of materials
     used in tests are not changed)
 
 15-01-15 V.Ivanchenko (materials-V10-01-00)
 - G4Material, G4Element, G4Isotope - make arguments of stream

     assumed to create a new material as a copy
