I did a thorough check of everything we have compared to the project specifications and made a couple changes.  I put a bunch of comments in spots that I think we need to discuss to determine correctness.  Check the diff of this file to see where those comments are.  I was able to get different completion times by changing around the parameters to more extreme values such as 'pwd 15 1000 FCFS'.  The SJF and SRTF still had the same values, but were different from FCFS which is good.  I think the potential changes I found may fix that though.
