| * |
| * @param column_name. A list of column names to retrieve. This can be used similar to Memcached's "multi-get" feature |

| * and 'Jim' you can pass those column names as a list to fetch all three at once. |
| * @param slice_range. A SliceRange describing how to range, order, and/or limit the slice. |
