>
> Made acceptableOverheadRatio configurable
> Added bulk get to AbstractAppendingLongBuffer classes, for faster retrieval.
> Introduced a new variant, AppendingPackedLongBuffer which solely relies on
> PackedInts as a back-end. This new class is useful where people have
> non-negative numbers with a fairly uniform distribution over a fixed
> (limited) range. Ex. facets ordinals.
> To distinguish it from AppendingPackedLongBuffer, delta based
> AppendingLongBuffer was renamed to AppendingDeltaPackedLongBuffer
> Fixed an Issue with NullReader where it didn't respect it's valueCount in
> bulk gets.
