This folder contains 2 alternatives code
1) "execute" using the WSF_SERVICE interface, i.e
execute (req: WSF_REQUEST; res: WSF_RESPONSE)
do
...
end
2) "launcher" using the WSF_RESPONSE_SERVICE interface, but it uses a launcher to start the service, instead of inheriting from WSF_DEFAULT_SERVICE or WSF_DEFAULT_RESPONSE_SERVICE
