        Function: returns a new Bio::AlignIO object to handle clustalw files
        Returns : Bio::AlignIO::clustalw object
        Args    : -verbose => verbosity setting (-1, 0, 1, 2)
                  -file    => name of file to read in or to write, with ">"
                  -fh      => alternative to -file param - provide a filehandle

                                  in each line of the alignment (clustalw only)
                  -linelength=> alignment output line length (default 60)

   next_aln
        Title   : next_aln
        Usage   : $aln = $stream->next_aln()
        Function: returns the next alignment in the stream

   write_aln
        Title   : write_aln
        Usage   : $stream->write_aln(@aln)
        Function: writes the clustalw-format object (.aln) into the stream
        Returns : 1 for success and 0 for error
