Engine.io not usable in web workers #120
Description
Engine.io seems to rely on objects that are not available in web workers.
If I try to implement a test setup inside a web worker by using
importScripts('http://localhost:8080/engine.io.js');
the browser gives me an error: window is not defined.
Is there any chance of getting rid of these dependencies? Socket.io does work inside web workers, so I expected Engine.io to do so, too, since it is only part of Socket.io.
