Copy/Duplicate a GridFS Document #134

Thank you so much for the awesome package. Quick question, which I hope isn't stupid and I am not overlooking something. Is there a simply way of making a copy or duplicate of a document?

On the server you can simply pipe the readable stream returned by fc.findOneStream() into the writable stream returned by fc.upsertStream().

See the node docs if you haven't piped streams together before: https://nodejs.org/dist/latest-v4.x/docs/api/stream.html#stream_readable_pipe_destination_options

Don't mean to be too much of a pain, but I think I am missing something (a bit new to streams). I implemented something along these lines, and in the db it appears to have the correct params, but I am unable to download the file. Any guidance would be greatly appreciated! 

let script = fc.findOne(id);
let readable = fc.findOneStream({'_id': id});
let writable = fc.upsertStream({
    'filename': script.filename,
    'metadata': {'_auth': {'owner': script.metadata._auth.owner} }
});
readable.pipe(writable);

** Nevermind, I have a stupid error somewhere but that works. Thank you so much for your help!
