* @predicate_uri_strings: configuration predicate URIs to look for
*
* Constructor - Make a new SQL configuration for a layout from a file
*
* Uses SQL storage name @storage_name and with database schema
* @layout to give a configuration that will contain an array of
* string values in the #librdf_sql_config field values array.
*
* Return value: configuration or NULL on failure
