   It works great.  Tested various things.
   
   one problem is with compression level 9 it caused my VM to hit oome.  This was because I had default heap size 512MB and because level 9 uses a large dictionary.  As a result we should warn users that this processor can be memory intensive.  It is bounded which is great so this is good.
   
   Also tested various file sizes and that levels matter.  Higher levels take longer and are marginally more efficient.  Lower levels are extremely fast and marginally more efficient.  As expected so is useful.
