/**
* A slice range is a structure that stores basic range, ordering and limit
* information for a query that will return multiple columns. It could be
* thought of as Cassandra's version of LIMIT and ORDER BY
*
* @param start
* . The column name to start the slice with. This attribute is not
* required, though there is no default value, and can be safely set
* to '', i.e., an empty byte array, to start with the first column
* name. Otherwise, it must a valid value under the rules of the
* Comparator defined for the given ColumnFamily.
* @param finish
* . The column name to stop the slice at. This attribute is not
* required, though there is no default value, and can be safely set
* to an empty byte array to not stop until 'count' results are seen.
* Otherwise, it must also be a value value to the ColumnFamily
* Comparator.
* @param reversed
* . Whether the results should be ordered in reversed order. Similar
* to ORDER BY blah DESC in SQL.
* @param count
* . How many keys to return. Similar to LIMIT 100 in SQL. May be
* arbitrarily large, but Thrift will materialize the whole result
* into memory before returning it to the client, so be aware that
* you may be better served by iterating through slices by passing
* the last value of one call in as the 'start' of the next instead
* of increasing 'count' arbitrarily large.
