/**
* The DateLocale class is a container and base class for all
* localised date strings used by YAHOO.util.Date. It is used
* internally, but may be extended to provide new date localisations.
*
* To create your own DateLocale, follow these steps:
* <ol>
* <li>Find an existing locale that matches closely with your needs</li>
* <li>Use this as your base class. Use YAHOO.util.DateLocale if nothing
* matches.</li>
* <li>Create your own class as an extension of the base class using
* YAHOO.lang.merge, and add your own localisations where needed.</li>
* </ol>
* See the YAHOO.util.DateLocale['en-US'] and YAHOO.util.DateLocale['en-GB']
* classes which extend YAHOO.util.DateLocale['en'].
*
* For example, to implement locales for French french and Canadian french,
* we would do the following:
* <ol>
* <li>For French french, we have no existing similar locale, so use
* YAHOO.util.DateLocale as the base, and extend it:
* <pre>
* YAHOO.util.DateLocale['fr'] = YAHOO.lang.merge(YAHOO.util.DateLocale, {
* a: ['dim', 'lun', 'mar', 'mer', 'jeu', 'ven', 'sam'],
* A: ['dimanche', 'lundi', 'mardi', 'mercredi', 'jeudi', 'vendredi', 'samedi'],
* b: ['jan', 'fév', 'mar', 'avr', 'mai', 'jun', 'jui', 'aoû', 'sep', 'oct', 'nov', 'déc'],
* B: ['janvier', 'février', 'mars', 'avril', 'mai', 'juin', 'juillet', 'août', 'septembre', 'octobre', 'novembre', 'décembre'],
* c: '%a %d %b %Y %T %Z',
* p: ['', ''],
* P: ['', ''],
* x: '%d.%m.%Y',
* X: '%T'
* });
* </pre>
* </li>
* <li>For Canadian french, we start with French french and change the meaning of \%x:
* <pre>
* YAHOO.util.DateLocale['fr-CA'] = YAHOO.lang.merge(YAHOO.util.DateLocale['fr'], {
* x: '%Y-%m-%d'
* });
* </pre>
* </li>
* </ol>
*
* With that, you can use your new locales:
* <pre>
* var d = new Date("2008/04/22");
* YAHOO.util.Date.format(d, {format: "%A, %d %B == %x"}, "fr");
* </pre>
* will return:
* <pre>
* mardi, 22 avril == 22.04.2008
* </pre>
* And
* <pre>
* YAHOO.util.Date.format(d, {format: "%A, %d %B == %x"}, "fr-CA");
* </pre>
* Will return:
* <pre>
* mardi, 22 avril == 2008-04-22
* </pre>
