  Adding the _atom_site_type_symbol data item to prevent confusion
  between carbon and calcium atoms.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value '1/\s(F~o~^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(F~o~^2^)'.
