100/100. Had issues with Rate limiting from github

I think i got all of the scripts right, but I had some issues with rate limiting from the github website. For the third mongo challenge I let it go to error when i tried to input a null value when I was rate limited, and for the fourth challenge I just used a local json file that I had got from week 4 because the rate limiting was so annoying. All the code should work though and I will be happy to redo the assignment if you feel I didn't earn my 100.
