57 * This class is supposed to parse a Stockholm format file into Jalview There
58 * are TODOs in this class: we do not know what the database source and version
59 * is for the file when parsing the #GS= AC tag which associates accessions with
60 * sequences. Database references are also not parsed correctly: a separate
61 * reference string parser must be added to parse the database reference form
62 * into Jalview's local representation.
