-  CppBindingExample class:
-  This provides an example of how to use the CppBoundClass to create methods
-  and properties that can be exposed to JavaScript by an appropriately built
-  embedding client. It is also used by the CppBoundClass unit test.
-
-  Typically, a class intended to be bound to JavaScript will define a
-  constructor, any methods and properties to be exposed, and optionally a
-  destructor.  An embedding client can then bind the class to a JavaScript
-  object in a frame's window using the CppBoundClass::BindToJavascript() method,
-  generally called from the WebFrameClient's DidClearWindowObject().
-
-  Once this class has been bound, say to the name "example", it might be called
-  from JavaScript in the following way:
-
-  <script>
-    if (window.example) {
-      document.writeln(example.echoValue(false));
-      document.writeln(example.echoType("Hello world!"));
-      document.writeln(example.plus(2, 3.1));
-
-      example.my_value = 15;
-      example.my_other_value = 2.1;
-      document.writeln(example.plus(example.my_value, example.my_other_value));
-    }
-  </script>
