1. Acknowledgements

I would love to take the opportunity to thank all who have reviewed and spotted issues in the manuscript. This includes but is not limited to Ngozi Nwosu for taking the time out to review the whole manual and point out a whole load of grammatical errors, Olivia Enewally, Roman Turna and Abhen Ng for pointing out some factual and grammatical errors.A whole lot of other people on Reddit have pointed out errors and to those people I am really grateful.

Without the input of all these people, this manuscript would be worth less than it currently is. Thank you all!
