GetChildObject(ObjectPath)

This method returns a reference to a child object pointed by the ObjectPath parameter. Then users can access all properties and methods of that object, similar to the GetObject method. This method fails if the path pointed by the ObjectPath parameter contains a property or method at its end. The path pointed by the child object is not a path starting at root (the .prj file) but instead a path starting at the object where this method is called.
