+/** 
+ * In a chain of data manipulators some behaviour is common. TableMap
+ * provides most of this behavour and can be subclassed by filters
+ * that only need to override a handful of specific methods. TableMap 
+ * implements TableModel by routing all requests to its model, and
+ * TableModelListener by routing all events to its listeners. Inserting 
+ * a TableMap which has not been subclassed into a chain of table filters 
+ * should have no effect.
