> A common question in the dist-lists is how to construct rowkeys, particularly composite
keys.  Put/Get/Scan specifies byte[] as the rowkey, but it's up to you to sensibly populate
that byte-array, and that's where things tend to go off the rails.
> The intent of this RowKey utility class isn't meant to add functionality into Put/Get/Scan,
but rather make it simpler for folks to construct said arrays.  Example:
> {code}
>    RowKey key = RowKey.create(RowKey.SIZEOF_MD5_HASH + RowKey.SIZEOF_LONG);
>    key.addHash(a);
>    key.add(b);
>    byte bytes[] = key.getBytes();
> {code}
