Issue #81 - Multiple WSDL's

Not quite sure on how to run your unit test, so I ran against my own set and passed. But if you could run against yours that would be great.

Basically, needed to move the req and response objects into being the standard express way of doing it (ie server.get() and server.post() ). By doing this, the app no longer needs to remove listeners, which was limiting it to just one service at a time.
