/**
* Google Cloud Pub/Sub is a globally distributed message bus that automatically scales as you need it.
* You can create a function ({@link onMessagePublished}) that handles pub/sub events by using functions.pubsub.
*
* This function triggers whenever a new pub/sub message is sent to a specific topic.
* You must specify the Pub/Sub topic name that you want to trigger your function, and set the event within the
* onPublish() event handler.
*
* PubSub Topic:
* <ul>
*   <li>A resource that you can publish messages to and then consume those messages via subscriptions.
*   <li>An isolated data stream for pub/sub messages.
*   <li>Messages are published to a topic.
*   <li>Messages are listened to via a subscription.
*   <li>Each subscription listens to the messages published to exactly one topic.
*
* Subscriptions - Resource that listens to the messages published by exactly one topic.
*
