// FirstPersonControl.js
//
// FirstPersonControl creates a control scheme where the camera 
// location and controls directly map to being in the first person.
// The left pad is used to move the character, and the
// right pad is used to rotate the character. A quick double-tap
// on the right joystick will make the character jump.
//
// If no right pad is assigned, then tilt is used for rotation
// you double tap the left pad to jump
