// A context represents additional information included with user input or with
// an intent returned by the Dialogflow API. Contexts are helpful for
// differentiating user input which may be vague or have a different meaning
// depending on additional details from your application such as user setting
// and preferences, previous user input, where the user is in your application,
// geographic location, and so on.
//
// You can include contexts as input parameters of a
// [DetectIntent][google.cloud.dialogflow.v2.Sessions.DetectIntent] (or
// [StreamingDetectIntent][google.cloud.dialogflow.v2.Sessions.StreamingDetectIntent]) request,
// or as output contexts included in the returned intent.
// Contexts expire when an intent is matched, after the number of `DetectIntent`
// requests specified by the `lifespan_count` parameter, or after 10 minutes
// if no intents are matched for a `DetectIntent` request.
//
// For more information about contexts, see the
// [Dialogflow documentation](https://dialogflow.com/docs/contexts).
