Ending Kevin's Reign

Added papers. "listings" package did not work for me, for some reason
"listing" did, I added my student number to the TeX files and made a
"listings" version in case anyone else gets this problem.

Wrote some rants about pure maths.
Edited the readme slightly.

I aim to write an intuitive and short (yey) introduction to groups/lie
groups. There will be no rigorous definitions just using ideas like: you
know what a differentiable function is, etc.
