RunStats class final

What a run came to, counted off the events it produced.

The results screen every game wrote by hand. Three applications counted kills, coins and laps, each in its own field, each cleared in its own place and each wrong in its own way — a count that carried between levels, a count reset by a restart that should have survived, a count nothing ever showed. What they had in common was that every one of them was reading the same thing: how many of a kind of moment happened.

So this counts events. A genre hands it what a step reported and it adds up what it recognises — which is nothing until a game says what to recognise, because a template that knew ShotFired would be a template that knew about weapons.

Named counters rather than fields, which is the same reading Tally takes: a game that counts something this package never heard of adds a line rather than a class.
