// Penelope iPhone Tutorial
//
// CameraRelativeControl creates a control scheme similar to what
// might be found in 3rd person platformer games found on consoles.
// The left stick is used to move the character, and the right
// stick is used to rotate the camera around the character.
// A quick double-tap on the right joystick will make the 
// character jump.
