Bug Fixes
* Fix a bug in histogram drawing (OLOGRAM).
API/CLI Changes
Code changes
* OLOGRAM doc has been updated.
* Added test for Beta distribution fitting.
New Features
* OLOGRAM now gives the p-value for S as fitted through a Beta distribution. However, Beta distributions are harder to fit, since
unavoidable small errors in the estimation of the skewness and kurtosis will propagate. In practice it is preferable to approximate this with a Negative Binomial. This will be explained in the manuscript.
