 If you run your application now with `node -r ./tracing.js app.js`, your application will create and propagate traces over HTTP. If an already instrumented service that supports [Trace Context](https://www.w3.org/TR/trace-context/) headers calls your application using HTTP, and you call another application using HTTP, the Trace Context headers will be correctly propagated.
