       This is a simple Bio::SeqFeatureI object that represents the query part of a SAM alignment.

   Methods
       $seqid = $query->seq_id
           The name of the read.

       $name = $query->name
           The read name (same as seq_id in this case).

       $name = $query->display_name
           The read display_name (same as seq_id in this case).

       $tag = $query->primary_tag
           The string "match".

       $tag = $query->source_tag
           The string "sam/bam".

       $start = $query->start
           The start of the match in read coordinates.

       $end = $query->end
           The end of the match in read coordinates;

       $len = $query->length
           The length of the read.

       $seq = $query->seq
           A Bio::PrimarySeq representing the read sequence in REFERENCE orientation.

       $scores = $query->qscore
           The  read  quality scores. In a list context, a list of integers equal in length to the read sequence
           length. In a scalar context, an array ref. The qscores are in REFERENCE sequence orientation.

       $dna = $query->dna
           The DNA string in reference sequence orientation.

       $strand = $query->strand
           If the query was reversed to align it, -1. Otherwise +1.

       $seq = $query->subseq($start,$end)
           Return a Bio::PrimarySeq object representing the requested subsequence on the read.
