Made the preliminary changes to the Kings db following the project meeting today. This is the SQL:

/**
* Changes to Kings DB made July 2011.
**/

/* Add the new field to three tables. */
ALTER TABLE monarchs ADD mn_dateInfo VARCHAR(128) AFTER mn_notAfter;
ALTER TABLE refs ADD rf_dateInfo VARCHAR(128) AFTER rf_notAfter;
ALTER TABLE sources ADD sc_dateInfo VARCHAR(128) AFTER sc_notAfter;

/* Delete the old datePrecision field from the three tables, along with 
   its associated table. */
  
ALTER TABLE monarchs DROP FOREIGN KEY mn_datePrecision_fk;
ALTER TABLE monarchs DROP mn_datePrecision;

ALTER TABLE refs DROP FOREIGN KEY rf_datePrecision_fk;
ALTER TABLE refs DROP rf_datePrecision;

ALTER TABLE sources DROP FOREIGN KEY sc_datePrecision_fk;
ALTER TABLE sources DROP sc_datePrecision;

DROP TABLE datePrecisions;

Parallel changes were made to local_classes.php.
