API Added a printf-like format() method
0.09 Fri Dec 11 2015

API Add noize_thresh clone arg to remove small bins
API Add clone() args (min, max, data, etc)

0.08 Tue May 12 2015
API Change default base 10**1/48 (~5%) => 10**1/232 (~1%);
API Remove broken mode() method, replace with a naive one
that at least works for discrete distributions;
API add_data_hash() can be used to forget data if needed;
API Add cdf(x,y) for probability of value between x and y;
BUG Make all methods return undef if there's no data;
DOC Add more examples to POD: basic usage, save/load, histogram;
DOC Add examples/save-load.pl (works with JSON files);
DOC Cleanup examples (summary, png) in examples directory;
DOC Add README.md for github
0.07 Mon Apr 27 2015
DOC Rename buckets => bins in POD and comments
API Add linear approximation approximation around zero
('linear_width' and 'linear_thresh' parameters in new())
API Add TO_JSON() method which returns unblessed hash
API Add 'data' parameter to new() to add initial data
API Deprecate old zero handling (zero_thresh)
0.06 Wed Jul 10 2013
TST Add png example
API Add histogram() - better frequency_distribution_ref
API Add scale_sample() to gradually "forget" data
API Add find_boundaries to get (min, max) of selected sample part
0.0509 Tue Jul 2 2013
DOC Minor POD improvement
BUG Make infinity portable
0.0507 Sun Jun 30 2013
