+/**
+This CLplGenericProxy class provides the default behavior for proxy classes.
+
+The default behaviour is to pass the calls on without any action to the
+Persistence Broker or Transaction Manager.
+
+The proxy controls all the basic operations on the database (such as Create,
+Read, Update and Delete) and transaction management operations.
+
+Future implementations of the proxy classes could extend the business rules of
+the contacts model or even plugin alternative data sources.  All these
+implementations should derive from this base class.
