* Cluster sample
* The problem was that the sent job was sometimes sent to deadLetters
* The reason was that statsService was not created when a facade
at another node forwared the job to the statsService, i.e.
deadLetters
* Solved by using ask and recover with JobFailed in case of
timeout in the facade, so that the facade always sends back
JobResult or JobFailed
* 2 Sample applications with main programs to play with,
and multi-node tests to illustrate testing, and
code snippets for inclusion in rst docs
* TransformationSample illustratates subscription to
cluster events
* StatsSample illustrates usage of cluster aware routers, both
lookup and deploy
