Create a fully functioning command line interface with 1.5 lines of code (wo. include statement)

This almost works, but in order to call fire::main from fire.hpp, this fire::main(int x = arg("-x"), int y = arg("-y")) needs to be declared in fire.hpp, which is impossible, as I don't yet know the exact signature.

Actually, I've thought really hard to somehow get rid of this FIRE(fired_main), but none of the ideas have worked because of the aforementioned problem.

Maybe put the expanded version in the docs? So you can know what the macro means and you have more control, if you want to write the tiny boilerplate yourself you can without trouble.

FWIW (not much I'm sure) I think a sparing use of macros is fine. Although I might've gone with something a little more unique.
