* Started integrating LameDuck into BPEL process.
* Now referencing LameDuck.xsd from TravelGood{wsdl,xsd}
* Changed return type of TravelGood.getFlights to match that of LameDuck.getFlights. Because of this:
    - Return type of getFlight now deviated from type contained in Itinerary. In tests, 'travels' is a list of 'FlightOption's, and 'itineraryTravels' is a list of 'Travel's
    - The class 'FlightOption' defined in test T.java refactored to 'FlightOptionPrivate' since it shadows 'FlightOption' class from LameDuck.
* Fixed a bug when building flightlist from csv file in T.java (TravelGoodTestSOAP), causing all entries in flight list to be from "Nice" to "Evil".
* Fixed a misordering of operators in getFlights operation in TravelGood.wsdl ((arrivalDestination, time, departureDestination) -> (source, time, destination)).
