> For HBASE-1172 and other functionality coming soon, we need to be able to
> take a [start,stop) range and divide it into chunks.
> For example, we have 10 regions but want to run 30 maps. We need to divide
> each region into three key ranges for the start/stop of each scanner.
> Implementing using java.math.BigInteger
> Will also include a couple additional helpers in Bytes to make life easy.
