docs: @class ServiceResponse
  
  used as a wrapper for all JSON responses.  This class has two main uses; 1) when a success
  response is to be returned, simply create and instance then attach the payload. 2) when a failure response needs
  to be returned, use the static constructor createFailedResponse() and pass in a reason and an optional failure
  code.
