 The example consists of the following files:
 
 person.hxx
-  Header file defining the 'basic_name', 'name_extras', and 'name' composite
-  value types. It also defines the 'phone_numbers' composite value type as
-  an instantiation of the 'std::pair' class template. Finally it defines

-  value types in its data members.
