/**
 * This is the basis of the internationalization system. Every single String that is visible to the
 * user should be translatet through this mechanism The text file messages.properties contains the
 * "generic" versions of all translatable Strings. To create a new language file, one must only
 * create a file called messages_<language>_locale.properties, where locale is optionale. Thus you
 * might create messages_fr.properties to create a french localization or messages_fr_CH.properties
 * to create an even more specific version
