An entity's preferred language.

A convenient type class to represent a preferred language of a user or session or whatever.

Use it in the companion object:

case class User(id: Int, lang: Lang)

object User {
 implicit object localized extends Localized[User] {
   override def locale(user: User) = user.lang
 }
}

Provides a helper for "localized" objects.

For example, for Messages:

Localized(user) { implicit lang =>
 Messages("error")
}

Messages externalization

== Overview == You would use it like so:

Localized(user) { implicit lang =>
 val error = Messages("error")
}

Messages are stored in messages_XXX.txt files in UTF-8 encoding in resources. The lookup will fallback to default file messages.txt if the string is not found in the language-specific file.

Messages are formatted with java.text.MessageFormat.
