Server#serveClient(v:Boolean):Server
If v is true the attached server (see Server#attach) will serve the client files. Defaults to true.
This method has no effect after attach is called.
// pass a server and the `serveClient` option
var io = require('socket.io')(http, { serveClient: false });
// or pass no server and then you can call the method
var io = require('socket.io')();
io.serveClient(false);
io.attach(http);
If no arguments are supplied this method returns the current value.
