michael@0:    This tests Object Hierarchy and Inheritance, as described in the document

michael@0:    This tests the syntax ObjectName.prototype = new PrototypeObject using the
michael@0:    Employee example in the document referenced above.
michael@0: 
michael@0:    If you add a property to an object in the prototype chain, instances of
michael@0:    objects that derive from that prototype should inherit that property, even
michael@0:    if they were instatiated after the property was added to the prototype object.
