-//     "turn on the light".
-//
-// *   **Events** - allow for matching an intent by using an event name

- *
- *  You can provide additional information for the Dialogflow API to use to
- *  match user input to an intent by adding the following to your intent.
- *
- *  *   **Contexts** - provide additional context for intent analysis. For
- *      example, if an intent is related to an object in your application that
- *      plays music, you can provide a context to determine when to match the
- *      intent if the user input is "turn it off". You can include a context
- *      that matches the intent when there is previous user input of
- *      "play music", and not when there is previous user input of
- *      "turn on the light".
- *
- *  *   **Events** - allow for matching an intent by using an event name
- *      instead of user input. Your application can provide an event name and
- *      related parameters to the Dialogflow API to match an intent. For
- *      example, when your application starts, you can send a welcome event
- *      with a user name parameter to the Dialogflow API to match an intent with
- *      a personalized welcome message for the user.
- *
- *  *   **Training phrases** - provide examples of user input to train the
- *      Dialogflow API agent to better match intents.
- *
- *  For more information about intents, see the
- *  [Dialogflow
- *  documentation](https://cloud.google.com/dialogflow/docs/intents-overview).
