 * Write a section to the Kernel I/O file.

 * Grid locations and possibly indexes may be assigned to a section by
 * specifying a location id; the first time a given location id appears in
 * the file is considered a declaration. In the same manner, an index id
 * may be specified. Values of zero indicate no location or index base
 * is used. It is up to the calling code to ensure that total number of
 * values, location size, and number of values per location are consistent,
 * as this my be important for code reading the file.

 *   name              <-- section name
 *   location_id       <-- id of associated location
 *   index_id          <-- id of associated index
 *   n_location_values <-- number of values per location
 *   embed             <-- embed values in header
