Score Objects

Scores are sortable objects that support an addition operator. Scores contain, and are ordered by:

1. total size of new files (increasing order),

2. the number of files (increasing order),

3. then computation time (decreasing order).

There is a value for a score object which is ordered after all legitimate values of score (i.e. all possible score values that could be derived from real data are better than this score).

Score values can be summed to generate the score of an aggregation of files.
