/**
* jQuery BASE64 functions
*
*
* Encodes the given data with base64.
* String $.base64Encode ( String str )
*
* Decodes a base64 encoded data.
* String $.base64Decode ( String str )
*
*
* 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
*
* $.base64Encode("I'm Persian.");
*
* Result
*
* "SSdtIFBlcnNpYW4u"
*
* Code
*
* $.base64Decode("SSdtIFBlcnNpYW4u");
*
* Result
*
* "I'm Persian."
