/**
* Agents are best described as Natural Language Understanding (NLU) modules
* that transform user requests into actionable data. You can include agents
* in your app, product, or service to determine user intent and respond to the
* user in a natural way.
*
* After you create an agent, you can add Intents, Contexts,
* Entity Types, Webhooks, and so on to
* manage the flow of a conversation and match user input to predefined intents
* and actions.
*
* You can create an agent using both Dialogflow Standard Edition and
* Dialogflow Enterprise Edition. For details, see
* [Dialogflow
* Editions](https://cloud.google.com/dialogflow/docs/editions).
*
* You can save your agent for backup or versioning by exporting the agent by
* using the ExportAgent method. You can import a saved
* agent by using the ImportAgent method.
*
* Dialogflow provides several
* [prebuilt
* agents](https://cloud.google.com/dialogflow/docs/agents-prebuilt)
* for common conversation scenarios such as determining a date and time,
* converting currency, and so on.
*
* For more information about agents, see the
* [Dialogflow
* documentation](https://cloud.google.com/dialogflow/docs/agents-overview).
