Internationalization
====================
Internationalization (I18N) refers to the process of designing a software application so that it can be adapted to
various languages and regions without engineering changes. For Web applications, this is of particular importance
because the potential users may be worldwide.
When developing an application it's assumed that we're relying on
[PHP internationalization extension](http://www.php.net/manual/en/intro.intl.php). While extension covers a lot of aspects
Yii adds a bit more:
- It handles message translation.
Locale and Language
