Return categorical thresholds used at node indexed by nodeIndex. If the considered input feature does NOT matche any of values returned by GetCategoricalSplitFeaturesAt(Int32), we call it a less-than-threshold event and therefore LeftChild[nodeIndex] is the child node that input should go next. The returned value is valid only if CategoricalSplitFlags[nodeIndex] is true.
