For the 1.2 release we'll differentiate between "drivers" and "examples".

> {{HITSAlgorithm}} tests for convergence by summing the difference of each authority score
minus the average score. This is simply comparing the sum of scores against the previous sum
of scores which is not a good test for convergence.
> {code}
> // count the diff value of sum of authority scores
> diffSumAggregator.aggregate(previousAuthAverage - newAuthorityValue.getValue());
> {code}
