example - A little CXFRS example

We need a little example to provide with the Camel kit, and documented at
http://camel.apache.org/examples

It should expose a simple REST service using CXF-RS, using JSon, and then invoke a bean where we can simulate a computation, and then prepare a response.
We could also do a little CBR in the Camel route etc. But the showcase is how to setup and use CXF-RS with Camel and use JSon.

Contributions is much welcome.
