     * This is the main file to make this program work it has some presaved users and rentables for the
     * part one to help with the testing here everything starts also most of the stuff work with
     * hashmaps wow they are practical! but it also uses the sub objects. For the first part it
     * will also have the login/register script but in the second part it will go in a diffrent file
     * like the user menus to help with the ui but other than that it is pretty clean in here 404 ftw!!
