/**
 * CLocalizedFormatter provides a set of commonly used data formatting methods based on the current locale settings.
 *
 * It provides the same functionality as {@link CFormatter}, but overrides all the settings for
 * {@link booleanFormat}, {@link datetimeFormat} and {@link numberFormat} with the values for the
 * current locale. Because of this you are not able to configure these properties for CLocalizedFormatter directly.
 * Date and time format can be adjsuted by setting {@link dateFormat} and {@link timeFormat}.
 *
 * It uses {@link CApplication::locale} by default but you can set a custom locale by using {@link setLocale}-method.
 *
 * For a list of recognizable format types, and details on how to call the formatter methods,
 * see {@link CFormatter} documentation.
 *
 * To replace the application component 'format', which is registered by {@link CApplication} by default, you can
 * put this in your application 'components' config:
 * <code>
 * 'format' => array(
 *     'class' => 'CLocalizedFormatter',
 * ),
 * </code>
