/**
* Object wrapper for outputing information from a shell application.
* Can be connected to any stream resource that can be used with fopen()
*
* Can generate colourzied output on consoles that support it. There are a few
* built in styles
*
* - `error` Error messages. Bright red text.
* - `warning` Warning messages. Bright orange text
* - `info` Informational messages. Cyan text.
*
* By defining styles with addStyle() you can create custom console styles.
*
* ### Using styles in output
*
* You can format console output using tags with the name of the style to apply. From inside a shell object
*
* `$this->out('<warning>Overwrite:</warning> foo.php was overwritten.');`
*
* This would create orange 'Overwrite:' text, while the rest of the text would remain the normal colour.
* See ConsoleOutput::styles() to learn more about defining your own styles.
