commands are now run in a subshell, this is often needed for chains of commands
where it is not the main command to need the privilege but a subcommand does,
for example
us echo 30 > /sys/class/backlight/*/brightness
it is not echo that needs the elevated privilege but the redirection '>' does.
added two files,
TODO: things that still need to be taken care of that may be too long to
write in the source code
config.template: mockups of the config file
