this should make testdir_munging_summary_runit_NOPASS_summary2_numeric.R pass. it's 1st quantile comcomparison between h2o and R for summary2 estimate was > the expected error bounds. added wonkysummary.csv to test_summary2_unifiles2.py. Fixed a bad decision, should keep the guess within the expected error bounds ((max-min)/1000)/2). Showed up when large jump from the max of the desired bin, to the next bins min (was using the next bin's min, for the interpolation endpt, for the estimate. This doesn't effect any multipass. just summary2 and single pass quantile (estimates).
