= HttpAcceptLanguage
A small effort in making a plugin which helps you detect the users preferred language, as sent by the HTTP header.
== Features
* Splits the http-header into languages specified by the user
* Returns empty array if header is illformed.
* Corrects case to xx-XX
* Sorted by priority given, as much as possible.
* Gives you the most important language
* Gives compatible languages
