## Description

Bio::FastaDefline is a parser class for definition line (defline) of the FASTA format.

## Examples

          rub = Bio::FastaDefline.new('>gi|671595|emb|CAA85678.1| rubisco large subunit [Perovskia abrotanoides]')
          rub.entry_id       ==> 'gi|671595'
          rub.get('emb')     ==> 'CAA85678.1'
          rub.emb            ==> 'CAA85678.1'
          rub.gi             ==> '671595'
          rub.accession      ==> 'CAA85678'
          rub.accessions     ==> [ 'CAA85678' ]
          rub.acc_version    ==> 'CAA85678.1'
          rub.locus          ==> nil
          rub.list_ids       ==> [["gi", "671595"],

                                  ["Perovskia abrotanoides"]]
