HOMEWORK PROBLEM 9         INTRODUCTION TO Ada 95   586

  PURPOSE:      To learn more about Ada 95 object oriented programming
                and how to use it, some uses of child packages,
                class wide types, and polymorphism.

  END RESULT:   A complete Ada program that is a main procedure
                that WITH's a package you write containing more
                types of figures.

  PROBLEM:      Write a package that has a shape
                derived from the Figure type. Do minimum editing
                to a copy of the Rectangle_Pkg to make a Diamond_Pkg
                and define a Diamond type.  Add corresponding tests
                in the main procedure FigureC to test your
                Diamond type. 

  NOTE:         A diamond just has a height and width like a rectangle.
                This is meant to be easy. The extra credit is much
                harder.

  EXTRA CREDIT: Make a child package of the child package
                Figure_Pkg.Circle_Pkg for an ellipse. The package
                would be called Figure_Pkg.Circle_Pkg.Ellipse_Pkg .
                Make the type Ellipse from the type Circle by
                adding one item to the record called Y_Radius.
                Add the corresponding tests to FigureC for your
                new type Ellipse

  OBSERVE:      Watch the naming conventions. They get long.
