microbenchmark, bit64 (>= 4.0.0), ff (>= 4.0.0)
Provided are classes for boolean and skewed boolean vectors,
    fast boolean methods, fast unique and non-unique integer sorting,
    fast set operations on sorted and unsorted sets of integers, and
    foundations for ff (range index, compression, chunked processing).
