Single server queue simulation missing in resampling.py

[abhijitmjj]

Firstly, I would like to thank you for this course. Your teaching style is lucid and succinct. I have learnt a lot watching your videos and this liveLesson.
I would like to point out that the resampling code does not have single server queue simulation example.
