* already with Yasumi, or your own provider by giving the name of your class in the first parameter. Your provider
* class needs to implement the 'ProviderInterface' class.
*
* @param string $class holiday provider name
* @param int $year year for which the country provider needs to be created. Year needs to be a valid integer
* between 1000 and 9999.
* @param string $locale The locale to use. If empty we'll use the default locale (en_US)
*
* @throws RuntimeException If no such holiday provider is found
* @throws InvalidArgumentException if the year parameter is not between 1000 and 9999
* @throws UnknownLocaleException if the locale parameter is invalid
* @throws InvalidArgumentException if the holiday provider for the given country does not exist
*
* @return AbstractProvider An instance of class $class is created and returned
