      Description

      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:

         RowKey key = RowKey.create(RowKey.SIZEOF_MD5_HASH + RowKey.SIZEOF_LONG);
         key.addHash(a);
         key.add(b);
         byte bytes[] = key.getBytes();
