> In BKDReader$IndexTree, the private final variable negativeDeltas seems useless. It will be only used in BKDReader.readNodeData(), we use negativeDeltas[level * numIndexDims + splitDim] to check whether the current nod is left or right, but it can be replaced by isLeft which is the function parameter.
