 * Pre-trained TFLite coco-ssd object detection model.

 * ```js
 * // Load the model with options (optional).
 * const model = await tfTask.ObjectDetection.CocoSsd.TFLite.load();
 *
 * // Run inference on an image.
 * const img = document.querySelector('img');
 * const result = await model.predict(img);
 * console.log(result.objects);
 *
 * // Clean up.
 * model.cleanUp();

 *
 * Refer to `tfTask.ObjectDetector` for the `predict` and `cleanUp` method.
