> HBase implicitly stores timestamp for each cell. Sometimes this feature is used to track historical data. I would like to provide option for HBaseStorage  which would return cell timestamp in milliseconds
> Interface:
> add option "withTimestamp" to HBaseStorage constructor
> Implementation:
> add timestamp:long as last element of tuple.
> RFC.
