> In DecisionTree, the method
> sequentialBinSearchForOrderedCategoricalFeatureInClassification() indexed
> bins from 0 to (math.pow(2, featureCategories.toInt - 1) - 1). This upper
> bound is the bound for unordered categorical features, not ordered ones. The
> upper bound should be the arity (i.e., max value) of the feature.
