Přidal jsem hromadu user-friendly funkcí do API (konzole, čas, paměť, vstup, procesy, AsterFS, string helpery), plus jsem to celé napojil i do syscall vrstvy, aby to drželo pohromadě i do budoucna pro user-space.\n\nDělal jsem to ve stejném stylu komentářů jako zbytek projektu a nechal jsem tam praktické helpery, které pokryjí většinu běžných app use-casů bez zbytečného boilerplate.
