/**
 * Function for handling controller based locomotion in VR
 * @param target Either an `Object`, or a callback function. Recieves translation and rotation input (required).
 * @param translationOptions Options that control the translation of the user. Set to `false` to disable.
 * @param translationOptions.speed The speed at which the user moves.
 * @param rotationOptions Options that control the rotation of the user. Set to `false` to disable.
 * @param rotationOptions.deadZone How far the joystick must be pushed to trigger a turn.
 * @param rotationOptions.type Controls how rotation using the controller functions. Can be either 'smooth' or 'snap'.
 * @param rotationOptions.degrees If `type` is 'snap', this specifies the number of degrees to snap the user's view by.
 * @param rotationOptions.speed If `type` is 'smooth', this specifies the speed at which the user's view rotates.
 * @param translationControllerHand Specifies which hand will control the translation. Can be either 'left' or 'right'.
