the class ScoreAccounting method evaluateAll.

    // however, for live it is absolutely mandatory to use depth first since using breadth first
    // the score accoutings local cache hash map will never be used. this can slow down things like
    // crazy (course with 10 tests, 300 users and some crazy score and passed calculations will have
    // 10 time performance differences)
