     * expandPattern( options, cldr )
     *
     * @options [Object] if String, it's considered a skeleton. Object accepts:
     * - skeleton: [String] lookup availableFormat;
     * - date: [String] ( "full" | "long" | "medium" | "short" );
     * - time: [String] ( "full" | "long" | "medium" | "short" );
     * - datetime: [String] ( "full" | "long" | "medium" | "short" );
     * - raw: [String] For more info see datetime/format.js.
     *
     * @cldr [Cldr instance].
     *
     * Return the corresponding pattern.
     * Eg for "en":
     * - "GyMMMd" returns "MMM d, y G";
     * - { skeleton: "GyMMMd" } returns "MMM d, y G";
     * - { date: "full" } returns "EEEE, MMMM d, y";
     * - { time: "full" } returns "h:mm:ss a zzzz";
     * - { datetime: "full" } returns "EEEE, MMMM d, y 'at' h:mm:ss a zzzz";
     * - { raw: "dd/mm" } returns "dd/mm";
