/**
 * Provides locale-neutral access to string resources.  Only the
 * documentation and code are in English. :-)
 *
 * 
The major goal, aside from globalization, is convenience.
 * Access to resources with no parameters is made in the form:
 *  *     Resources.getMessage(MESSAGE_NAME);
 * 
 *
 * Access to resources with one parameter works like
 *  *     Resources.getMessage(MESSAGE_NAME, arg1);
 * 
 *
 * ... and so on.
