+ * A LaunchDarkly context object.  LaunchDarkly contexts are objects representing users, devices, organizations, and

+ * You can manage how contexts interact with your app by targeting flag variations to specific contexts, based on

+ * what variation to serve. You can be as specific as targeting a flag to a single end context, or as broad as targeting
+ * your entire customer base. You can even use anonymous contexts and private attributes to control what data to
