- Updated version to 2.0.1

- MAJOR change in jHiccup log format:
    - Changed ot using a single log file, in HdrHistogram histogram log format.
    - Added jHiccupLogProcessor (and/using org.jhiccup.HistogramLogProcessor) to post process hlog into previous log output form.

 - Now able to produce percentile distribution for arbitrary range in jHiccup log.
     - This is *extremely* useful for production logging and answering the:
        "What was the hiccup percentile distribution yesterday between 8AM and 9AM" question

- Tools (and people or scripts) that rely on previous log format can still get it by using jHiccupLogProcessor.

- jHiccup log is now directly readable with org.HdrHistogram.HistogramLogReader
