Changing the output color of HtmlDumper
----------------------------------------

The :class:`Symfony\\Component\\VarDumper\\Dumper\\HtmlDumper` class added a new :method:`Symfony\\Component\\VarDumper\\Dumper\\HtmlDumper::setTheme` method. Now you can use both ``'dark'`` and ``'light'`` options.

Example::

require __DIR__.'/vendor/autoload.php';

use Symfony\Component\VarDumper\VarDumper;
use Symfony\Component\VarDumper\Dumper\HtmlDumper;
use Symfony\Component\VarDumper\Cloner\VarCloner;

$varDumper = new VarDumper();
$varDumper::setHandler();

$cloner = new VarCloner();

$htmlDumper = new HtmlDumper();
$htmlDumper->setTheme('light');

VarDumper::setHandler(function ($var) use ($cloner, $htmlDumper) {
$htmlDumper->dump($cloner->cloneVar($var));
});

$data = [
'Now',
'this',
'should be',
'lighter!',
];

dump($data);
