9.  def getBestRealSplit[T](data: Seq[(Vector[AnyVal], T, Double)], calculator: ImpurityCalculator[T], index: Int, minCount: Int, randomizePivotLocation: Boolean = false, rng: Random = Random): (Split, Double)

   Find the best split on a continuous variable.

   Find the best split on a continuous variable. This is a typical implementation for decision trees: it finds the pivot that maximizes the decrease in impurity. Some splitters might forego this method and implement different ways of choosing a pivot point.

   data

   to split

   index

   of the feature to split on

   minCount

   minimum number of data points to allow in each of the resulting splits

   randomizePivotLocation

   whether generate splits by drawing a random value uniformly between the two split points. This can improve generalizability, particularly as part of an ensemble.

   returns

   the best split of this feature
