+/**
+ * Configuration array Helper.
+ * 
+ * The {{luya\Config}} allowy you to create the configuration for different hosts and between web and console config.
+ * 
+ * ```php
+ * // base config which is the same for all envs, console and web
+ * Config::base(['id' => 'myapp', 'basePath' => dirname(__DIR__)]);
+ * ```
+ * 
+ * Register modules:
+ * 
+ * ```php
+ * Config::module('admin', ['class' => 'luya\admin\Module', 'secureLogin' => false]);
+ * Config::module('cms', 'luya\cms\frontend\Module'); // Same as: ['class' => 'luya\cms\frontend\Module']
+ * ```
+ * 
+ * Setup components based on the env:
+ * 
+ * ```php
+ * // prod database
+ * Config::component('db', [
+ *     'class' => 'yii\db\Connection',
+ *     'dsn' => 'mysql:host=localhost;dbname=prod_db',
+ *     'username' => 'foo',
+ *     'password' => 'bar',
+ * ], Config::ENV_PROD);
+ * 
+ * // local database
+ * Config::component('db', [
+ *     'class' => 'yii\db\Connection',
+ *     'dsn' => 'mysql:host=localhost;dbname=local_db',
+ *     'username' => 'foo',
+ *     'password' => 'bar',
+ * ], Config::ENV_LOCAL);
+ * ```
+ * 
+ * Switch between console and web application:
+ * 
+ * ```php
+ * Config::web([
+ *     'components' => [
+ *         'request' => [
+ *             'luya\web\Request' => [
+ *                 'cookieValidationKey' => '123123123123123123123',
+ *             ]
+ *         ]
+ *     ]
+ * ]);
+ * ```
+ * 
+ * Configurations from {{luya\Config::web()}} and {{luya\Config::console()}} will override predefined configurations
+ * from {{luya\Config::base()}}.
