Inherit "symbol" from first entity of newly constructed "Alias"
attribute (where we place primary symbol at top of the list); add
"Aliasl", "Computational_description", "Curator_summary", "conf_class"
and "conf_rating" to desired set of feature type (make changes to the
`aip-gff_additions.xml` and the aip-gff GFF3 RecordHandler)
