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