Found the bug in the engine: RodLocusView was using the wrong seek method so that it would only move to the first locus of a shard (and with multi-locus shards, this meant that we never processed RODs from the other positions). In fact, because the seek(Shard) method is extremely misleading and now no longer used, I think it's safer to delete it and make everyone use the much more transparent seek(GenomeLoc). Note that I have not re-enabled my improvements to the intervals accumulation of ReferenceDataSource because that inefficiency is still present downstream in RodLocusView; need to discuss those changes with Matt.
