<?php

/**
 * A "Locale" is an identifier used to get language, culture, or regionally-specific 
 * behavior from an API. PHP locales are organized and identified the same
 * way that the CLDR locales used by ICU (and many vendors of Unix-like operating 
 * systems, the Mac, Java, and so forth) use. Locales are identified using
 * RFC 4646 language tags (which use hyphen, not underscore) in addition to the
 * more traditional underscore-using identifiers. Unless otherwise noted
 * the functions in this class are tolerant of both formats. 
 *
 * Examples of identifiers include:
 *
 *  * en-US (English, United States)
 *  * zh-Hant-TW (Chinese, Traditional Script, Taiwan)
 *  * fr-CA, fr-FR (French for Canada and France respectively) 
 *
 * The Locale class (and related procedural functions) are used to interact 
 * with locale identifiers--to verify that an ID is well-formed, valid, 
 * etc. The extensions used by CLDR in UAX #35 (and inherited by ICU) are 
 * valid and used wherever they would be in ICU normally.
 *
 * Locales cannot be instantiated as objects. All of the functions/methods 
 * provided are static.
 *
 *   * The null or empty string obtains the "root" locale. 
 *     The "root" locale is equivalent to "en_US_POSIX" in CLDR.
 *   * Language tags (and thus locale identifiers) are case insensitive. There
 *     exists a canonicalization function to make case match the specification.
 *
