X-Description: fast multi-dimensional unboxed bit packed Bool arrays
 Unboxed multidimensional bit packed Bool arrays with fast aggregate
 operations based on lifting Bool operations to bitwise operations.
 .
 There are many other bit packed structures out there, but none met
 all of these requirements:
 .
 (1) unboxed bit packed Bool array,
 .
 (2) multi-dimensional indexing,
 .
 (3) fast (de)serialization, or interoperable with foreign code,
 .
 (4) fast aggregate operations (fold, map, zip).
 .
 Quick tour of the bitwise library:
 .
 [Data.Bits.Bitwise] Lift boolean operations on 'Bool' to bitwise
 operations on 'Data.Bits.Bits'.
 .
 [Data.Array.BitArray] Immutable bit arrays.
 .
 [Data.Array.BitArray.ST] Mutable bit arrays in 'Control.Monad.ST.ST'.
 .
 [Data.Array.BitArray.IO] Mutable bit arrays in 'IO'.
 .
 [Data.Array.BitArray.ByteString] (De)serialization.
 .
 [Codec.Image.PBM] Portable bitmap monochrome 2D image format.
 .
 Very rough performance benchmarks:
 .
 * immutable random access single bit reads:
 @BitArray ix@ is about 40% slower than @UArray ix Bool@,
 .
 * 'Control.Monad.ST.ST' mutable random access single bit reads:
 @STBitArray s ix@ is about the same as @STUArray s ix Bool@,
 .
 * immutable map @Bool -> Bool@:
 @BitArray ix@ is about 85x faster than @UArray ix Bool@,
 .
 * immutable zipWith @Bool -> Bool -> Bool@:
 @BitArray ix@ is about 1300x faster than @UArray ix Bool@.
