/**
 * 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 valid 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 columns to return. Similar to LIMIT 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.
