Logging

[fh-ms]

To achieve better useability we will add logging to the core modules.

We only log against a facade (slf4j), not a logger implementation to provide the best flexibility for our users.

See branch feature/logging_slf4j

Feel free to comment on this issue, to collect ideas where logging can be of interest.

• Logging the mircostream version at startup would be fine too

Need to specify in detail what could be logged in AFS.
