"Gamepad" Input example for Wekinator, e.g. for Xbox 360 controller

Gamepad_Eyes_OSC.pde

// Gamepad_Eyes_OSC: demo of using game controller for OSC input. 
// Uses the two thumb-sticks and either the left or right bumper buttons. 
//
// Peter Lager maintains the Game Control Plus library (for Processing),
// which provides control data for joysticks and other game controllers
// ...such as my Xbox 360 controller. 
//
// This is a quick mash-up using Lager's Gcp_gamepad animated eyes example code, 
// (which is in the GCP library:  In Processing, go to File > Examples..., then Contributed Libraries > Game Control Plus)
// and Rebecca Fiebrink's Simple_Mouse_DraggedObject_2Inputs example code for Wekinator. 
//
// Required Processing libraries: Game Control Plus, oscP5.  Also needs Lager's file "data/gamepad_eyes" text file from his example. 
//
// See Lager's website & videos at  http://lagers.org.uk/gamecontrol/ for more info.
