This class implements the `Hello World' service.
It inherits from WSF_DEFAULT_SERVICE to get default EWF connector ready
only `response' needs to be implemented.
In this example, it is redefined and specialized to be WSF_PAGE_RESPONSE
`initialize' can be redefine to provide custom options if needed.
