*
* There are three primary motivations for this particular implementation.
* 1) Programmer's pride. I wanted to be able to say I'd done it, and I
* wanted to learn from the experience.
* 2) Portability. I wanted an implementation that I knew to be portable
* to a reasonable number of platforms. In particular, the algorithm is
* designed with little-endian platforms in mind, but I wanted an

* 3) Compactness. While not an overriding goal, I thought it worth-while
