> FilterEstimation.scala use EstimationUtils#numBinsHoldingRange() to calculate
> how many bins in the range.While there is a small logical issue, when
> calculating lowerPart, if lowerBin.hi equals to lowerBound and
> lowerBoundInclusive is false, then lowerPart should be 0, but now it is
> 1/lowerBin.ndv . Similarly higherPart.
