/** A service discovery function for the Javascript Nashorn engine.

* for a particular category of services. Right now, the list of services are known a-priori
* and specified as interfaces (e.g. GSNInterface.js) that context aware accessor can include using the
* 'implement' function.
*
* The known services are obtained via the services() function which is implemented
* by the method availableServices() in the helper class.
