tscore reads all the .tde files in the current directory (normally register.tde and 1.tde,
etc for each round of the tournament) and calculates the scores and summaries for the entire tournament.
If a ##ROUNDS directive is provided in the register.tde file,
tscore can adjust the results to reflect the total number of rounds expected.
tscore normally scores by number of won games,
with SOS as the first tie break,
SODS as the second tie breaker,
and Head-to-head as the third tie breaker.
Note that Head-to-head is limited because (for example),
there can be a head-to-head lockout if A beats B,
B beats C,
and C beats A.
