Day 4 Monte Carlo integration

Firstly, access the working directory for this exercise:

~/WORKSHOP/Day_4/MC_Tutorial

Then open MC-integration.ipynb, and follow the instructions. There is a second notebook, MC-Lennard-Jones.ipynb, which you may move on to whenever you like, and indeed you can start with this one if you prefer. A third notebook, MC-Pressure.ipynb is for a subsequent workshop.
