crepes 0.3.0

Features

• The class DifficultyEstimator was added to crepes.fillings, incorporating functionality provided by the previous functions sigma_knn, sigma_knn_oob, sigma_variance, and sigma_variance_oob, which now are superfluous and have been removed from crepes.fillings. See the documentation for the interface to objects of the class through the fit and apply methods.

• An option to normalize difficulty estimates, by providing scaler=True to the fit method of DifficultyEstimator, has been included.

Fixes

• The Jupyter notebook crepes_nb.ipynb has been updated to incorporate the above features

• The documentation of the crepes package and the crepes.fillings module has been updated with links to source code, additional examples and notes.
