 * No K&R coding style. Braces {} should be on their own line, aligned with the parent statement.
 * No public variables, always use public properties unless there is no other workaround.
 * Properties should be camel case, no underscores (e.g. public bool IsReady { get; set; }).
-* Constants should be all PascalCase (e.g. static readonly string ConfigFile = "/Config.json"). This includes enumerations.
 * All public functions and types of all classes should be fully documented using the XML comment style.
 * Local variables should be camel case. (e.g. var speechToText = new SpeechToText())
 * Use protected on variables & functions only if you plan to inherit from the class or there is a good chance we will need to be polymorphic.

 You can write an authentication proxy in IBM® Bluemix® that obtains and returns a token to your client application, which can then use the token to call the service directly. This proxy eliminates the need to channel all service requests through an intermediate server-side application, which is otherwise necessary to avoid exposing your service credentials from your client application.
