	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 '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
