## Proposed API

### Code

```php
// Symfony command
protected function execute(InputInterface $input, OutputInterface $output)
{
    $output = new OutputDecorator($output);

    $output->title('Lorem Ipsum Dolor Sit Amet');
    $output->text(array(
        'Duis aute irure dolor in reprehenderit in voluptate velit esse',
        'cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat'
    ));
    $output->ln();

    // TODO table

    $output->caution('Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris.');
    $output->subtitle('Consectetur Adipisicing Elit Sed Do Eiusmod');
    $output->listing(array(
        'Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod, tempor incididunt ut labore et dolore magna aliqua.',
        'Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo.',
        'Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.'
    ));

    // TODO questions

    $output->note('Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat.');
    $output->success('Lorem ipsum dolor sit amet, consectetur adipisicing elit');
    $output->error('Duis aute irure dolor in reprehenderit in voluptate velit esse.');
    $output->warning('Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi.');
}
```

### Expected Output

```
$ php app/console command

Lorem Ipsum Dolor Sit Amet
==========================

 // Duis aute irure dolor in reprehenderit in voluptate velit esse
 // cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat

### Issues

- `Table` helper cannot render the required style - will need major refactor
- `QuestionHelper` needs to be updated
To avoid confusion with the `-v|-vv|-vvv` options, maybe we should drop the *"debug text"* part of this description. This method outputs regular text, so "Informational text" could be enough.
