Class to simplify use of internationalization message strings. Property files are constructed in terms of content as for JAI with one "key=value" pair per line. All such files however have the same name "properties". The resource extractor resolves the extraction of the file from the jar as the package name is included automatically.

Extenders need only provide a static method getString(String) which calls the static method in this class with the name of the invoking class and returns a String.
