* 1. Cloud Functions allows wildcards in the `path` name. Any `path` component
* in curly brackets (`{}`) is a wildcard that matches all strings. The value
* that matched a certain invocation of a Cloud Function is returned as part
* of the `context.params` object. For example, `ref("messages/{messageId}")`
* matches changes at `/messages/message1` or `/messages/message2`, resulting
* in `context.params.messageId` being set to `"message1"` or `"message2"`,
* respectively.
* 2. Cloud Functions do not fire an event for data that already existed before
* the Cloud Function was deployed.
* 3. Cloud Function events have access to more information, including information
* about the user who triggered the Cloud Function.
