      Description

      Our ByteRange interface has some nice properties such as a compareTo method using hbase-friendly unsigned byte comparison. This can be backed by either on-heap or off-heap byte buffers. Consider an allocator that internally allocates huge on or off-heap slabs and hands out ByteRanges over portions of those arenas. Keep it as simple as possible, optimized for HBase needs. Can be fairly standalone with respect to the rest of the HBase code.
