Have aggregate query scores summed instead of averaged for the gain based metrics

[david-fisher]

Is your feature request related to a problem? Please describe. The aggregate score for the set of queries in the case shows the average of the scores for each of the queries. This is not very meaningful for the gain based metrics, CG and DCG.

Describe the solution you'd like Those two metrics could be summed up, instead of average, giving a clearer picture of the change in the full case when updating judgments on a query.

Describe alternatives you've considered None Additional context
