/**
 * Immutable class that picks the best match between a user's desired locales and
 * an application's supported locales.
 * Movable but not copyable.
 *
 * <p>Example:
 * <pre>
 * UErrorCode errorCode = U_ZERO_ERROR;
 * LocaleMatcher matcher = LocaleMatcher::Builder().setSupportedLocales("fr, en-GB, en").build(errorCode);
 * Locale *bestSupported = matcher.getBestLocale(Locale.US, errorCode);  // "en"
 * </pre>
 *
 * <p>A matcher takes into account when languages are close to one another,
 * such as Danish and Norwegian,
 * and when regional variants are close, like en-GB and en-AU as opposed to en-US.
 *
 * <p>If there are multiple supported locales with the same (language, script, region)
 * likely subtags, then the current implementation returns the first of those locales.
 * It ignores variant subtags (except for pseudolocale variants) and extensions.
 * This may change in future versions.
 *
 * <p>For example, the current implementation does not distinguish between
 * de, de-DE, de-Latn, de-1901, de-u-co-phonebk.
 *
 * <p>If you prefer one equivalent locale over another, then provide only the preferred one,
 * or place it earlier in the list of supported locales.
 *
 * <p>Otherwise, the order of supported locales may have no effect on the best-match results.
 * The current implementation compares each desired locale with supported locales
 * in the following order:
 * 1. Default locale, if supported;
 * 2. CLDR "paradigm locales" like en-GB and es-419;
 * 3. other supported locales.
 * This may change in future versions.
 *
 * <p>Often a product will just need one matcher instance, built with the languages
 * that it supports. However, it may want multiple instances with different
 * default languages based on additional information, such as the domain.
 *
 * <p>This class is not intended for public subclassing.
