  Program : inheritanceWebPage.java
  Purpose : This program uses multiple classes to make use of
            INHERITANCE.

            The class cssDefault.java is called the SUPER-CLASS and 
            contains some methods that are inherited by other 
            classes, by using the extends command in their signature.

            The classes WebPageHome, WebPage2, and WebPage3 are 
            called SUB-CLASSES because they inherit/extends from the
            cssDefault SUPER-CLASS.

            These SUB-CLASSES can use all the methods of the SUPER-
            CLASS. At the same time these classes can have methods 
            with the same names used in the SUPER-CLASS with 
            different content. If a SUB-CLASS does this it is said
            that it is OVERIDING such method(s). SUB-CLASSES can have
            their own additional methods, not found in the SUPER-
            CLASS.

            The calling program that uses a SUB-CLASS, first checks  
            to see if there are methods with the same name in the
            SUPER-CLASS, if there are, it will use the methods inside 
            the SUB-CLASS overriding the methods in the SUPER-CLASS.
