-- The NanoSchedule timing code (in NSRuntimeProfile) was crazy expensive, but never showed up in the profilers. Removed all of the timing code from the NanoScheduler, the NSRuntimeProfile itself, and updated the unit tests.
-- For tools that largely pass through data quickly, this change reduces runtimes by as much as 10x. For the RealignerTargetCreator example, the runtime before this commit was 3 hours, and after is 30 minutes (6x improvement).
-- Took this opportunity to improve the GATK ProgressMeter. NotifyOfProgress now just keeps track of the maximum position seen, and a separate daemon thread ProgressMeterDaemon periodically wakes up and prints the current progress. This removes all inner loop calls to the GATK timers.
-- The history of the bug started here: http://gatkforums.broadinstitute.org/discussion/comment/2402#Comment_2402
-- Providing this optional argument -maxRuntime (in -maxRuntimeUnits units) causes the GATK to exit gracefully when the max. runtime has been exceeded. By cleanly I mean that the engine simply stops at the next available cycle in the walker as through the end of processing had been reached. This means that all output files are closed properly, etc.
-- Emits an info message that looks like "INFO 10:36:52,723 MicroScheduler - Aborting execution (cleanly) because the runtime has exceeded the requested maximum 10.0000 s". Otherwise there's currently no way to differentiate a truly completed run from a timelimit exceeded run, which may be a useful thing for a future update
-- Resolves GSA-630 / GATK max runtime to deal with bad LSA calling?
-- Added new JIRA entry for Ami to restart chr1 macarthur with this argument set to -maxRuntime 1 -maxRuntimeUnits DAYS to see if we can do all of chr1 in one weekend.
-- TraversalProgressMeter now completely generalized, named ProgressMeter in utils.progressmeter. Now just takes "nRecordsProcessed" as an argument to print reads. Completely removes dependence on complex data structures from TraversalProgressMeter. Can be used to measure progress on any task with processing units in genomic locations.
-- a fairly simple, class with no dependency on GATK engine or other features.
-- Currently only used by the TraversalEngine / MicroScheduler but could be used for any purpose now, really.
