ArithmeQuiz - BETA version

(**Fanfare**) Here is the BETA version of the ArithmeQuiz! - the KPI based infinite question generator for the Maths Club Members.

As Steve said on the LeadMeet, we are working to "try and break it" - so please let us know if you spot anything that needs editing and we will iron these imperfections out ASAP.

The infinite question generator is up and running and ready to use! However, please be aware that the downloads are not as 'pretty' as we'd like at the moment, so we are currently making improvements on those. They are available, but not perfect yet.

Thank you for your patience. We really hope you find this useful.
