nibblestring

Packed, strict nibble arrays with a list interface (ByteString for nibbles)

Data.NibbleString holds an array of Nibbles (4-bit values), and provides an interface similar to that in Data.ByteString. Although similar to Bytestring, there are obvious differences. The "length" of a nibblestring will be twice that of bytestring, unpacking a nibblestring will result in two items per byte, etc. Data.NibbleString is intended to be imported qualified.
