replace commons logging with slf4j?

[GoogleCodeExporter]

It is much better to use slf4j than commons logging. It is possible for 
everyone to stick to their chosen implementation. As most frameworks use slf4j 
it is quite a hassle to work around commons logging using a dummy 
implementation.

Also note this article: http://articles.qos.ch/thinkAgain.html and the 
references at the bottom.

Agreed. Having libraries use slf4j as their facade simplifies integration, and 
the existence of slf4j-jcl means projects that want to stick with 
commons-logging just need to include that to bridge across.

The APIs are similar enough that the change is simply a matter of changing the 
logger definitions and importing the dependencies; patch attached.

On top of this, it may be worth using slf4j's parameterised logging to remove 
the 'if (DEBUG)' checks.
