PubSub Publisher documentation missing options documentation

[lc-chrisbarton]

For a Cloud Function I need to immediately publish and so I assume I need to set maxMessages=1 and maxMilliseconds=0 when calling pubsub.topic(...).publisher({ batching: { maxMessages: 1, maxMilliseconds: 0 } }) but this is not documented and I needed to look at the source (which was fine but I hope I have made the correct assumption about how to setup immediate send):

https://googlecloudplatform.github.io/google-cloud-node/#/docs/pubsub/0.14.0/pubsub/publisher?method=Publisher

The documentation is available on the topic though:
https://googlecloudplatform.github.io/google-cloud-node/#/docs/pubsub/0.14.0/pubsub/topic?method=publisher

https://github.com/GoogleCloudPlatform/google-cloud-node/blob/pubsub-0.14.0/packages/pubsub/src/topic.js

• @param {number} options.batching.maxMessages - The maximum number of messages

• to buffer before sending a payload.
  

• @param {number} options.batching.maxMilliseconds - The maximum duration to

• wait before sending a payload.
