# Example negotiator implementation, which randomly chooses to accept
# an offer or return with a randomized counteroffer.
# Important things to note: We always set self.offer to be equal to whatever
# we eventually pick as our offer. This is necessary for utility computation.
# Second, note that we ensure that we never accept an offer of "None".
