/**
 * Configuration array Helper.

 * The {{luya\Config}} allows you to create the configuration for different hosts and difference between web and console config.
 * 
 * ```php
 * $config = new Config('myapp', dirname(__DIR__), [
 *     'siteTitle' => 'My LUYA Project',
 *     'defaultRoute' => 'cms',
 *     // other application level configurations
 * ]);
 * 
 * // define global components which works either for console or web runtime
 * 
 * $config->component('mail', [
 *     'host' => 'xyz',
 *     'from' => '[email protected]',
 * ]);
 * 
 * $config->component('db', [
 *     'class' => 'yii\db\Connection',
 *     'dsn' => 'mysql:host=localhost;dbname=prod_db',
 *     'username' => 'foo',
 *     'password' => 'bar',
 * ]);
 * 
 * // define components which are only for web or console runtime:
 * 
 * $config->webComponent('request', [
 *     'cookieValidationKey' => 'xyz',
 * ]);
 * 
 * // which is equals to, but the above is better to read and structure in the config file
 * 
 * $config->component('request', [
 *     'cookieValidationKey' => 'xyz',
 * ])->webRuntime();
 * 
 * // adding modules
 * 
 * $config->module('admin', [
 *     'class' => 'luya\admin\Module',
 *     'secureLogin' => true,
 * ]);
 * 
 * $config->module('cms', 'luya\cms\frontend\Module'); // which is equals to $config->module('cms', ['class' => 'luya\cms\frontend\Module']);
 * 
 * // export and generate the config for a given enviroment or environment independent.
 * 
 * return $config->toArray(); // returns the config not taking care of enviroment variables like prod, env
 * 
 * return $config->toArray(Config::ENV_PROD);
 * ```
 * 
 * Switching between envs can be usefull if certain configurations should only apply on a certain environment. Therefore you can add `env()` behind componenets, applications and modules.
 * 
 * ```php
 * $config->component('db', [
 *     'class' => 'yii\db\Connection',
 *     'dsn' => 'mysql:host=localhost;dbname=prod_db',
