 Adding the _atom_site_type_symbol data item.

 Antanas Vaitkus,
 2017-01-19

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value '1/[\s^2^(F)+0.02973F^2^]' was
changed to 'calc'. New tag '_refine_ls_weighting_details' was
created. The value of the new tag was set to 'w =
1/[\s^2^(F)+0.02973F^2^]'.
