I'm not sure you'd want to remove this because it allows running the plugin outside the maven environment in debug.  This was key to finding out where my issue was.  Without this, I was unable to examine in debug outside of my own webapp that was using the fingerprint plugin.  This is critical to running the plugin for different people who are doing development on the plugin.  Recreating the environment, outside of an unknown webapp, is important so we're all on the same page.  We can recreate the issue in our artificial environment and be looking at the same thing.

This is why the src/test/fingered-web directory is created (and ignored by git) during the test run.  You get a chance to see the results run by the code.  And turn around for development is extremely fast.  Which makes us more productive.
