Since it will use less space if the bitset is sparse with occasional 0
or 1 bits, this sounds like a good choice for a nontype template
parameter. Obviously the user could just invert the sense of the bits
themselves (instead of representing presence in a set, it could
represent "lack of absence"), but a template parameter would be more
user-friendly. A converting constructor could be provided for
converting between the two.
