v0.16.0

• Breaking Change
  • Fix the sorting of the parameters in the feature names (#656)
    The feature names consist of a sorted list of all parameters now.
    That used to be true for all non-combiner features, and is now also true for combiner features.
    If you relied on the actual feature name, this is a breaking change.
  • Change the id after the rolling (#668)
    Now, the old id of your data is still kept. Additionally, we improved the way
    dataframes without a time column are rolled and how the new sub-time series
    are named.
    Also, the documentation was improved a lot.
• Added Features
  • Added variation coefficient (#654)
  • Added the datetimeindex explanation from the notebook to the docs (#661)
  • Optimize RelevantFeatureAugmenter to avoid re-extraction (#669)
  • Added a function add_sub_time_series_index (#666)
  • Added Dockerfile
  • Speed optimizations and speed testing script (#681)
• Bugfixes
  • Increase the extracted ar coefficients to the full parameter range. (#662)
  • Documentation fixes (#663, #664, #665)
  • Rewrote the sample_entropy feature calculator (#681)
    It is now faster and (hopefully) more correct.
    But your results will change!
