Feature: Min/Max with variable number of arguments

[Xenos-Interactive]

Please give min(), max() or argmin, argmax with more than two inputs. I want to compare like 8 variables at once with each other. Reye said it is called variadic input.

I will keep that in mind, it should be simple and I will add it as soon as I have time, I am in the middle of giang PRs and that shoudl be done after those.
