code: function RestorerStream (qlobber)
  {
      stream.Writable.call(this, { objectMode: true });
      this._restorer = qlobber.get_restorer();
  }
docs: Creates a new [`Writable`](https://nodejs.org/dist/latest-v8.x/docs/api/stream.html#stream_class_stream_writable) stream, in object mode, which passes data written to it into the function returned by calling [`get_restorer`](#qlobberprototypeget_restoreroptions) on a qlobber.
  
  You could [`pipe`](https://nodejs.org/dist/latest-v8.x/docs/api/stream.html#stream_readable_pipe_destination_options) a [`JSONStream.parse`](https://github.com/dominictarr/JSONStream#jsonstreamparsepath) stream to this, for instance, to deserialize the qlobber from JSON. See [this test](test/json.js#L33) for an example.
  
  Inherits from [`Writable`](https://nodejs.org/dist/latest-v8.x/docs/api/stream.html#stream_class_stream_writable).
