25    Description:        new PrototypeObject
26
27    This tests Object Hierarchy and Inheritance, as described in the document
28    Object Hierarchy and Inheritance in JavaScript, last modified on 12/18/97

32    This tests the syntax ObjectName.prototype = new PrototypeObject using the
33    Employee example in the document referenced above.
34
35    If you add a property to an object in the prototype chain, instances of
36    objects that derive from that prototype should inherit that property, even
37    if they were instatiated after the property was added to the prototype object.
