// This class maps integer id's to Strings used in the user interface
// screens of the MIDlet. It is meant as a simple placeholder for
// internationalization support.
//
// Currently, the default (and only) language supported is "en-US".
// The class could be extended to support other mappings in the future,
// although it currently supports just one.
//
// (Note: A few simple strings used in CloseableCanvas like ":", "(", ")",
// numeric strings, and white space like " " or "\n" are not translated
// by the Dictionary. If those would need internationalization support,
// then appropriate support would need to be added.)

    //    TEXT : text strings that are 'contents' of some screen, i.e. drawn
    //           in the game screen or used in the instructions screen
