 Usage   : my $obj = Bio::SearchIO::Writer::GbrowseGFF->new(@args);
 Function: Builds a new Bio::SearchIO::Writer::GbrowseGFF object
 Returns : an instance of Bio::SearchIO::Writer::GbrowseGFF
 Args    :  -e_value => 10   : set e_value parsing cutoff (default undef)
            (note the -e_value flag is deprecated.)

to_string

 Purpose   : Produce the Gbrowse format GFF lines for a Result
