 Changing the value of the _atom_site_type_symbol data
 item for hydrogen atoms from '?' to 'H'.

 Antanas Vaitkus,
 2017-01-15

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'w = 1' was changed to 'calc'.
New tag '_refine_ls_weighting_details' was created. The value of the
new tag was set to 'w = 1'.
