    Description

      OneHotEncoder should be an Estimator, just like in scikit-learn (http://scikit-learn.org/stable/modules/generated/sklearn.preprocessing.OneHotEncoder.html).
      In its current form, it is impossible to use when number of categories is different between training dataset and test dataset.
