)abbrev domain BITS Bits
++ Author: Stephen M. Watt
++ Description:
++ \spadtype{Bits} provides logical functions for Indexed Bits.

Bits() : SIG == CODE where

  SIG ==> BitAggregate() with

    bits : (NonNegativeInteger, Boolean) -> %
      ++ bits(n,b) creates bits with n values of b

  CODE ==> IndexedBits(1) add

    bits(n,b)    == new(n,b)
