[Cs5500] Reputation computing

[Daniel Marcucci]

Hi Sapna,

To answer your first question, I believe the qualities here are the quality
from the claim (i.e., C) and the quality from the solution (i.e., C').
Therefore, when computing the result, you take the absolute value of the
difference between those two qualities then add or subtract reputation
accordingly (i.e., the |quality(C)-quality(C')| portion of the formula will
be the same for both players but how it is factored into their new
reputation will depend on who won and who lost).

To answer your second question, I think you would confirm the strengthening
based on the protocol that was described in the rules document (
http://www.ccs.neu.edu/home/lieber/courses/se-courses/cs5500/sp11/projects/rules/rules
).

I could be wrong on both of these, so I would appreciate it if others could
correct any mistakes I may have made. Thanks.
