=head1 NAME
Bio::DB::Bam::Target -- Object representing the query portion of a BAM/SAM alignment in NATIVE alignment
=head1 SYNOPSIS
This is identical to Bio::DB::Bam::Query, except that the dna, qscores
and start and end positions are all given in the orientation in which
the read was sequenced, not in the oreintation in which it was
aligned.
