     *         String $.base64Encode ( String str )
     *        <br />
     *         Decodes a base64 encoded data.

     *     </code>
     * 
     * Encodes and Decodes the given data in base64.
     * This encoding is designed to make binary data survive transport through transport layers that are not 8-bit clean, such as mail bodies.
     * Base64-encoded data takes about 33% more space than the original data. 
     * This javascript code is used to encode / decode data using base64 (this encoding is designed to make binary data survive transport through transport layers that are not 8-bit clean). Script is fully compatible with UTF-8 encoding. You can use base64 encoded data as simple encryption mechanism.
     * If you plan using UTF-8 encoding in your project don't forget to set the page encoding to UTF-8 (Content-Type meta tag). 
     * This function orginally get from the WebToolkit and rewrite for using as the jQuery plugin.
     * 
     * Example
     *     Code
     *         <code>
     *             $.base64Encode("I'm Persian."); 
     *         </code>
     *     Result
     *         <code>
     *             "SSdtIFBlcnNpYW4u"
     *         </code>
     *     Code
     *         <code>
     *             $.base64Decode("SSdtIFBlcnNpYW4u");
     *         </code>
