This is almost identical to an {@link Object3D}. Its purpose is to
make working with groups of objects syntactically clearer.

```js
// Create a group and add the two cubes.
// These cubes can now be rotated / scaled etc as a group.
const group = new THREE.Group();

group.add( meshA );
group.add( meshB );

scene.add( group );
```
