Extended Submission Deadline for Assignment (3b)

Because we are a little behind in our lecture schedule, we are extending the submission deadline for our final obligatory problem set to the end of the day (midnight) on Thusday this week (November 17).  For the theoretical parts of question (4), we are missing some background on the inner workings of the generalized chart parsing framework; and even though it should be possible to work things out from just the code (with its generous comments), this part of the assignment will (hopefully) be much clearer after our final lecture on chart parsing this Thursday.
