Access theme configuration

Accessing the theme configuration is rather simple. Every view gets passed to an instance method to access configuration values. A simple code sample is shown below:

<?= $this->config('group_name', 'config_name') ?>

This small code snippet will return either a string or a boolean, based on the type you configured in your theme.php. If you access a configuration you have not set in your theme.php a PHP warning is output.
