Also format all files and add a flake.lock for lib for a folder thats meant to work on other flakes theres never a reason it should need to refer to itself, only other flakes. So "self" and "inputs" are better namings for these variables. The userFlake* is redundant and confusing, when trying to call the functions its hard to figure out how to use them when there are now two lines of arguments to figure out.
