=head1 NAME

Bio::Tools::HMMER::Set - Set of identical domains from HMMER matches

=head1 SYNOPSIS

    # get a Set object probably from the results object
    print "Bits score over set ",$set->bits," evalue ",$set->evalue,"\n";

    foreach $domain ( $set->each_Domain ) {
	print "Domain start ",$domain->start," end ",$domain->end,"\n";
    }

=head1 DESCRIPTION

Represents a set of HMMER domains hitting one sequence. HMMER reports two
different scores, a per sequence total score (and evalue) and a per
domain score and evalue. This object represents a collection of the same
domain with the sequence bits score and evalue. (these attributes are also
on the per domain scores, which you can get there).
