 -- OBJECTIVE:
 --      Check that class-wide objects can be initialized using allocation. 
 --
 -- TEST DESCRIPTION:
 --      Declare access types that refer to class-wide types, one with basis
 --      of the root type, another with basis of a type extended from the root.
 --      Declare objects of these access types, and allocate class-wide
 --      objects, initialized to values of specific types within the particular
 --      classes.
 --
 --      The particular root and extended types used in this abstraction are
 --      defined in foundation code (F341A00.A), and are graphically displayed
 --      as follows:
 --
 --           package Bank
 --              type Account
 --                  |
 --                  |
 --                  |
 --               package Checking
 --                  type Account
 --                      |
 --                      |
 --                      | 
 --                   package Interest_Checking
 --                          type Account
 --
