wii.Controller subclasses
wii.Wiimote
This handler responds to traditional Wiimote presses.
wii.KeyboardController
This handler responds to keyboard inputs. This is useful for
testing your Wii-friendly web site in a PC web browser.
wii.HorizontalController
This handler responds as if the controller is being held horizontally
(with the D-pad on the left) like the traditional NES controller.
In this case, the 1 button corresponds to the B button
and the 2 button corresponds to the A button.
