-- Reuse infrastructure for RODs for reads to implement general IntervalReferenceOrderedView so that both TraverseReads and TraverseActiveRegions can use the same underlying infrastructure
-- TraverseActiveRegions now provides a meaningful RefMetaDataTracker to ActiveRegionWalker.map
-- Cleanup misc. code as it came up
-- Resolves GSA-808: Write general utility code to do rsID allele matching, hook up to UG and HC
Don't map class to counts in the ReadMetrics (necessitating 2 HashMap lookups for every increment).
Instead, wrap the ReadFilters with a counting version and then set those counts only when updating global metrics.
1. Don't clone the dataSource's metrics object (because then the engine won't continue to get updated counts)
2. Use the dataSource's metrics object in the CountingFilteringIterator and not the first shard's object!
3. Synchronize ReadMetrics.incrementMetrics to prevent race conditions.
Also:
* Make sure users realize that the read counts are approximate in the print outs.
* Removed a lot of unused cruft from the metrics object while I was in there.
* Added test to make sure that the ReadMetrics read count does not overflow ints.
* Added unit tests for traversal metrics (reads, loci, and active region traversals); these test counts of reads and records.
