    10    Description:        new PrototypeObject

    12    This tests Object Hierarchy and Inheritance, as described in the document

    13    Object Hierarchy and Inheritance in JavaScript, last modified on 12/18/97

    14    15:19:34 on http://devedge.netscape.com/.  Current URL:

    17    This tests the syntax ObjectName.prototype = new PrototypeObject using the

    18    Employee example in the document referenced above.

    20    If you add a property to an object in the prototype chain, instances of

    21    objects that derive from that prototype should inherit that property, even

    22    if they were instatiated after the property was added to the prototype object.
