      Description

      I think OpenBitSet is trying to satisfy too many audiences, and it's
      confusing/error-proned as a result. It has int/long variants of many
      methods. Some methods require in-bound access, others don't; of those
      others, some methods auto-grow the bits, some don't. OpenBitSet
      doesn't always know its numBits.

      I'd like to factor out a more "focused" bit set impl whose primary
      target usage is a cached Lucene Filter, ie a bit set indexed by docID
      (int, not long) whose size is known and fixed up front (backed by
      final long[]) and is always accessed in-bounds.
