In this update, I addressed Philip LaFrance's comments.  I also modified the definition of the HSS private key to include the public pub[] and sig[] arrays; those are kept around with the private key, and makes it easier to understand (even if they don't need to be kept secret)

> Abstract:
>    This note describes a digital signature system based on cryptographic
>    hash functions, following the seminal work in this area of Lamport,
>    Diffie, Winternitz, and Merkle, as adapted by Leighton and Micali in
>    1995.  It specifies a one-time signature scheme and a general
>    signature scheme.  These systems provide asymmetric authentication
>    without using large integer mathematics and can achieve a high
>    security level.  They are suitable for compact implementations, are
>    relatively simple to implement, and naturally resist side-channel
>    attacks.  Unlike most other signature systems, hash-based signatures
>    would still be secure even if it proves feasible for an attacker to
>    build a quantum computer.
