Automated extraction of elements in the dataset

All ranging definitions are post-processed by the parser to infer the elements. The set of unique chemical symbols for these elements is used to define the /ENTRY[entry*]/specimen/atom_types in the resulting NeXus/HDF5 file in accordance with the requirements that are defined by the NXapm application definition. NOMAD Oasis uses reads from this field during the nexus parsing stage into NOMAD metainfo to enable element-specific search capabilities via the periodic table widget.
