Create ghostwriter.io (the example that demonstrates GhostWriter in action)

[szabolcsmaj]

A basic github README is not enough to quickly explain what GW does and how this benefits the developers.

Create a web application for ghostwriter.io that demonstrates the feature of GhostWriter by displaying the tracing information the server side produces as you navigate ghostwriter.io. A simple RESTful Java service should do the trick.
Visitors of ghostwriter.io should seen the tracing generated by other visitors. The IP masking can be an example of @ghostwriter(ignore=true).
The site can also mention GhostWriter bootstrapping as well.
