/**
 *
 *
 * <pre>
 * Dialogflow contexts are similar to natural language context. If a person says
 * to you "they are orange", you need context in order to understand what "they"
 * is referring to. Similarly, for Dialogflow to handle an end-user expression
 * like that, it needs to be provided with context in order to correctly match
 * an intent.
 * Using contexts, you can control the flow of a conversation. You can configure
 * contexts for an intent by setting input and output contexts, which are
 * identified by string names. When an intent is matched, any configured output
 * contexts for that intent become active. While any contexts are active,
 * Dialogflow is more likely to match intents that are configured with input
 * contexts that correspond to the currently active contexts.
 * For more information about context, see the
 * [Contexts guide](https://cloud.google.com/dialogflow/docs/contexts-overview).
 * </pre>
