 This being said, there are definitively cases where attempting to use compressed bitmaps is wasteful.
 For example, if you have a small universe size. E.g., your bitmaps represent sets of integers
-from [0,n) where n is small (e.g., n=64 or n=128). If you are able to uncompressed BitSet and

 it does not blow up your memory usage,  then compressed bitmaps are probably not useful
 to you. In fact, if you do not need compression, then a BitSet offers remarkable speed.
 One of the downsides of a compressed bitmap like those provided by JavaEWAH is slower random access:
