Hello Dear Team Members

I'm pushing new module for your project . I'm adding language selection in header and now user can change language of your site .
I handle this module with directive named data-translate. I'm fully describe my module how is it work in datatraslate directive files, But I'm show you one example :

Projectsinfo is one of your keys defined in your language and when user change language , Our directive automatically read from key-value data and replace value.

Notice : I'm trying to read key-value from json files in localization folder but your project structure don't allow me for adding static files and read from them.
You can change my method in app.js. My method is changeLanguage in app.js and you can replace static data with reading from json language file with input language name. For example if user select "en" you must load from en.json in localization folder.

Good Luck
