Each of the sections labeled 1 to 8 contain relevant information on the topics listed below. 'PDF', 'HTML' and 'JNB' (Jupyter Notebook) folders contain the relevant files for each of the sections 1 to 8. Please note that the 'Extras' folder contains additional jpeg images as well as two small csv files. These may be needed for those who wish to run certain Jupyter Notebook files.
