/**
 * Introducing Gyro (gyroscope, on mobile) support for WebChucK. Gyro wraps
 * JavaScript `DeviceOrientationEvent` listeners easing access to mobile device
 * gyroscope in WebChucK code.
 *
 * To get started with Gyro:
 *
 * ```ts
 * import { Chuck, Gyro } from "webchuck";
 *
 * const theChuck = await Chuck.init([]);
 * const gyro = await Gyro.init(theChuck); // Initialize Gyro
 * ```
 *
 * The `deviceorientation` event gives motion of the device around the three
 * axes (x, y, and z) represented in degrees from 0 to 360. More on the
 * `deviceorientation` event can be found online
 * {@link https://developer.mozilla.org/en-US/docs/Web/API/Window/deviceorientation_event | here }.
 *
 * iOS devices require that the web developer ask permission from the user
 * to access sensors after a button push. This looks like:
 *
 * ```ts
 * let runButton = document.getElementById("run");
 *
 * runButton.addEventListener("click", async () => {
 *   // Request iOS gyroscope permission
 *   if (typeof DeviceOrientationEvent.requestPermission === 'function') {
 *     await DeviceOrientationEvent.requestPermission();
 *   }
 *
 *   await theChuck.loadFile("./yourChuckCode.ck");
 *   theChuck.runFile("yourChuckCode.ck");
 * });
 * ```
