Logging

Logging is a bit hacky, short term goals:

• Redirect the logging to log4j via slf4j log4j-12 binding

What is our long term goal for logging:

• Separate between the API and back-end, use SLF4J as the API.
• Get all logging into the same back-end. Just have one logging system.
• Do logging instead of Exception.printStacktrace() and System.out.
• Log4j is no actively longer being maintained, swap to http://logback.qos.ch/ as our backend.
