> Now that row keys are byte arrays, users should be able to specify a comparator at table creation time.
> My use case for this is to implement secondary indexes. In this case, row keys for the index tables will be constructed from an optional prefix of the original row key as well as the content of column that is being indexed. Then the comparator will first compare based on the key prefix, and break ties by deserializing the column values and using the deserialized type's compareTo method.
