Function dipstick::stats_average

pub fn stats_average(
    kind: InputKind, 
    name: MetricName, 
    score: ScoreType
) -> Option<(InputKind, MetricName, MetricValue)>

A predefined export strategy reporting the average value for every non-marker metric. Marker metrics export their hit count instead. Since there is only one stat per metric, there is no risk of collision and so exported stats copy their metric's name.
