Improve the implementation of Entrance.
Entrance.present() method doesn't accept any argument now. Instead, Entrance.gather(String...) is available, to collect the args, and after that, Entrance.parameter() series methods would help to fetch each parameter values. So the typical calling form of Entrance now is:
new Entrance().gather(args).present();
or
new Entrance().gather(args).parameter(someKey);
