/**
* An internationalization / localization helper class which reduces
* the bother of handling ResourceBundles and takes care of the
* common cases of message formating which otherwise require the
* creation of Object arrays and such.
*
* The StringManager operates on a package basis. One StringManager
* per package can be created and accessed via the getManager method
* call.
*
*
The StringManager will look for a ResourceBundle named by
* the package name given plus the suffix of "LocalStrings". In
* practice, this means that the localized information will be contained
* in a LocalStrings.properties file located in the package
* directory of the classpath.
*
*
Please see the documentation for java.util.ResourceBundle for
* more information.
