Standardized algorithm output log

I dont think we should do this with a printLn statement and rather use one of our loggers. Otherwise we definitely dont have it in WebOCDs logs for later viewing. Whats your opinion on that?

On another note, I think the Ant algorithm still prints its modularity apart from the final output. I'll double check the other files as well just to be sure

The point of this was to standardize console output since it differed among algorithms. But yeah, it makes more sense to use a logger and actually do it directly from the Serviceclass when calling the algorithm. I'll change that

Issues with logging

1. Logging number of communities found from within the service class (runAlgorithm method) requires waiting for the algorithm execution to finish, which would result in unnecessary blocking.
2. using L2pLogger only makes sense from within a service class, so using it from detectOverlappingCommunities method of OCD algorithms is not viable.
