### Output levels
There are 3 built-in output level. Shell::QUIET, Shell::NORMAL, Shell::VERBOSE.
The verbose and quiet output levels, map to the verbose and quiet output switches
present in most shells. Using Shell::QUIET for a message means it will always display.
While using Shell::VERBOSE means it will only display when verbose output is toggled.
