Related to bug 68. See also [1]

- As suggested by Ralph Goers on comment #5, migrating code from the
logback project, in particular the ch.qos.logback.classic.stopwatch
package to SLF4J. Since 99.9% of the code is logging system
independent, it makes sense to migrate this code to SLF4J, more
precisely into the newly created slf4j-ext module.

The profiler code has been extremely useful in measuring the
performance of a real-world project. 

Documentation to follow.
