CHOMPStation2/code/ATMOSPHERICS/components/trinary_devices/mixer.dm
Zulker Nayeen Nahiyan b6ab0b64c0 Cleanup global.dm and setup.dm, fix typos in the other files 
`code/setup.dm`:
	Fixed large amounts of indenting.
	Fixed large numbers of comments and their clarity.
	Added parentheses to macros using expressions.
	Added FIXME for unused duplicated macros, without certainty of their requirement.
	Removed some duplicate macros present. (`BRUTE`, `BURN`, etc.)
	Removed macro `PI`, and replaced instances of its use with `var/const/Pi` from `maths.dm`

`code/global.dm`:
	Fixed large amounts of indenting, added newlines to long single-lined list definitions.
	Slightly clarified comments.
