1.13 + Description: new PrototypeObject
1.14 +
1.15 + This tests Object Hierarchy and Inheritance, as described in the document
1.16 + Object Hierarchy and Inheritance in JavaScript, last modified on 12/18/97
1.17 + 15:19:34 on http://devedge.netscape.com/. Current URL:

1.19 +
1.20 + This tests the syntax ObjectName.prototype = new PrototypeObject using the
1.21 + Employee example in the document referenced above.
1.22 +
1.23 + If you add a property to an object in the prototype chain, instances of
1.24 + objects that derive from that prototype should inherit that property, even
1.25 + if they were instatiated after the property was added to the prototype object.
