/*
    This program was made for people who just want a simple and working autoclicker
    and also for devs who need to simulate inputs.

    REMINDER:
    This is a 1.0 version,
    for now if you want to chose which inputs you want to "simulate",
    please check the WinApi docs to find the macros that needs to be used in the structures.
