## 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"],
                            ["emb", "CAA85678.1", nil],
                            ["Perovskia abrotanoides"]]
