=head1 NAME

Bio::Assembly::Singlet - Perl module to hold and manipulate
                     singlets from sequence assembly contigs.

=head1 SYNOPSYS

    # Module loading
    use Bio::Assembly::IO;

    # Assembly loading methods
    $aio = new Bio::Assembly::IO(-file=>"test.ace.1",
                               -format=>'phrap');

    $assembly = $aio->next_assembly;
    foreach $singlet ($assembly->all_singlets) {
      # do something
    }

=head1 DESCRIPTION

A singlet is a sequence that phrap was unable to align to any other sequences.
