Previous output was not very usable in presence of decomposed
specifications. We now keep track of the number of parts, and also
prefix the columns names with "max_" or "sum_" to indicate how their
statistics are updated in presence of multiple part. Other missing
statistics, like the size of the translated automaton, or maximal
number of colors seen in a game, have been added.
