/**
 * A <code>Locale</code> object represents a specific geographical, political,
 * or cultural region. An operation that requires a <code>Locale</code> to perform
 * its task is called <em>locale-sensitive</em> and uses the <code>Locale</code>
 * to tailor information for the user. For example, displaying a number
 * is a locale-sensitive operation--the number should be formatted
 * according to the customs/conventions of the user's native country,
 * region, or culture.
 *
 * <P>
 * You create a <code>Locale</code> object using the constructor in
 * this class:
 * <blockquote>
 * <pre>
 * .      Locale( const   char*  language, 
 * .              const   char*  country, 
 * .              const   char*  variant);
 * </pre>
 * </blockquote>
 * The first argument to the constructors is a valid <STRONG>ISO
 * Language Code.</STRONG> These codes are the lower-case two-letter
 * codes as defined by ISO-639.
 * You can find a full list of these codes at a number of sites, such as:
 * <BR><a href ="http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt">
 * <code>http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt</code></a>
 *
 * <P>
 * The second argument to the constructors is a valid <STRONG>ISO Country
 * Code.</STRONG> These codes are the upper-case two-letter codes
 * as defined by ISO-3166.
 * You can find a full list of these codes at a number of sites, such as:
 * <BR><a href="http://www.chemie.fu-berlin.de/diverse/doc/ISO_3166.html">
 * <code>http://www.chemie.fu-berlin.de/diverse/doc/ISO_3166.html</code></a>
 *
 * <P>
 * The third constructor requires a third argument--the <STRONG>Variant.</STRONG>
 * The Variant codes are vendor and browser-specific.
 * For example, use WIN for Windows, MAC for Macintosh, and POSIX for POSIX.
 * Where there are two variants, separate them with an underscore, and
 * put the most important one first. For
 * example, a Traditional Spanish collation might be referenced, with
 * "ES", "ES", "Traditional_WIN".
 *
 * <P>
 * Because a <code>Locale</code> object is just an identifier for a region,
 * no validity check is performed when you construct a <code>Locale</code>.
 * If you want to see whether particular resources are available for the
 * <code>Locale</code> you construct, you must query those resources. For
 * example, ask the <code>NumberFormat</code> for the locales it supports
 * using its <code>getAvailableLocales</code> method.
 * <BR><STRONG>Note:</STRONG> When you ask for a resource for a particular
 * locale, you get back the best available match, not necessarily
 * precisely what you asked for. For more information, look at
 * <a href="java.util.ResourceBundle.html"><code>ResourceBundle</code></a>.
 *
 * <P>
 * The <code>Locale</code> class provides a number of convenient constants
 * that you can use to create <code>Locale</code> objects for commonly used
 * locales. For example, the following refers to a <code>Locale</code> object
 * for the United States:
 * <blockquote>
 * <pre>
 *       Locale::getUS()
 * </pre>
 * </blockquote>
 *
 * <P>
 * Once you've created a <code>Locale</code> you can query it for information about
 * itself. Use <code>getCountry</code> to get the ISO Country Code and
 * <code>getLanguage</code> to get the ISO Language Code. You can
 * use <code>getDisplayCountry</code> to get the
 * name of the country suitable for displaying to the user. Similarly,
 * you can use <code>getDisplayLanguage</code> to get the name of
 * the language suitable for displaying to the user. Interestingly,
 * the <code>getDisplayXXX</code> methods are themselves locale-sensitive
 * and have two versions: one that uses the default locale and one
 * that takes a locale as an argument and displays the name or country in
 * a language appropriate to that locale.
 *
 * <P>
 * The TIFC provides a number of classes that perform locale-sensitive
 * operations. For example, the <code>NumberFormat</code> class formats
 * numbers, currency, or percentages in a locale-sensitive manner. Classes
 * such as <code>NumberFormat</code> have a number of convenience methods
 * for creating a default object of that type. For example, the
 * <code>NumberFormat</code> class provides these three convenience methods
 * for creating a default <code>NumberFormat</code> object:
 * <blockquote>
 * <pre>
 *     UErrorCode success = U_ZERO_ERROR;
 *     Locale myLocale;
 *     NumberFormat *nf;
 * 
 *     nf = NumberFormat::createInstance( success );          delete nf;
 *     nf = NumberFormat::createCurrencyInstance( success );  delete nf;
 *     nf = NumberFormat::createPercentInstance( success );   delete nf;
 * </pre>
 * </blockquote>
 * Each of these methods has two variants; one with an explicit locale
 * and one without; the latter using the default locale.
 * <blockquote>
 * <pre>
 *     nf = NumberFormat::createInstance( myLocale, success );          delete nf;
 *     nf = NumberFormat::createCurrencyInstance( myLocale, success );  delete nf;
 *     nf = NumberFormat::createPercentInstance( myLocale, success );   delete nf;
 * </pre>
 * </blockquote>
 * A <code>Locale</code> is the mechanism for identifying the kind of object
 * (<code>NumberFormat</code>) that you would like to get. The locale is
 * <STRONG>just</STRONG> a mechanism for identifying objects,
 * <STRONG>not</STRONG> a container for the objects themselves.
 *
 * <P>
 * Each class that performs locale-sensitive operations allows you
 * to get all the available objects of that type. You can sift
 * through these objects by language, country, or variant,
 * and use the display names to present a menu to the user.
 * For example, you can create a menu of all the collation objects
 * suitable for a given language. Such classes implement these
 * three class methods:
 * <blockquote>
 * <pre>
 *       static Locale* getAvailableLocales(int32_t& numLocales)
 *       static UnicodeString& getDisplayName(const Locale&  objectLocale,
 *                                            const Locale&  displayLocale,
 *                                            UnicodeString& displayName)
 *       static UnicodeString& getDisplayName(const Locale&  objectLocale,
 *                                            UnicodeString& displayName)
 * </pre>
 * </blockquote>
