History
Viktor Lofgren 8f522470ed (index) Adjust rank weightings to fix bad wikipedia results 
There was as bug where if the input of ResultValuator.normalize() was negative, it was truncated to zero.  This meant that "bad" results always rank the same.  The penalty factor "overallPart" was moved outside of the function and was re-weighted to accomplish a better normalization.

Some of the weights were also re-adjusted based on what appears to produce better results.  Needs evaluation.
