/**
* CURRENTLY NOT USED KEEPING FOR REFERENCE 9/19/2002
*
* Wrapper class for resource bundles. Property files are used to store resource strings, which
* are the only types of resources available. Property files can inherit properties from other files
* so that a base property file can be used and a small number of properties can be over-ridden by
* another property file. For example you may create an english version of a resource file named
* "resource.properties". You then decide that the British English version of all of the properties
* except one are the same, so there is no need to redefine all of the properties in
* "resource_en_GB", just the one that is different.
The property file lookup searches for
* classes with various suffixes on the basis if the desired local and the current default local (as
* returned by Local.getDefault()). As property files are found the property values are merged so
* that inheritance is preserved.
The order of searching is:
basename + "_" +
* langage + "_" + country + "_" + variant basename + "_" + langage + "_" + country basename + "_" +
* langage basename + "_" + defaultLanguage + "_" + defaultCountry + "_" + defaultVariant basename +
* "_" + defaultLanguage + "_" + defaultCountry basename + "_" + defaultLanguage basename
* The basename is the name of the property file without the ".properties" extension.
* Properties will be cached for performance.
Property values stored in the property files
* can also contain dynamic variables. Any dynamic variable defined in
* PropertiesUtil.getVariableValue() can be used (such as {date}), as well as arguments in the form
* {0}, {1}, etc. Argument values are specified in the various overloaded getString() methods.
