Theres a line in the receive function I want to understand better so we can make it not look like a straight up copy.

timeSent = struct.unpack("d", recPacket[28:28 + 8])[0]

I changed it a little bit, but I feel we can make it look more different.

The code is basically the same as the others. I'm not sure why it wasn't working on campus but at my apartment I'm getting pongs back. Need to try this on a hardline in the CEC lab to see if it works there as she emailed us saying it needs to work on those machines.
