/**

* Converts to and from JSON format.

*

* JSON (JavaScript Object Notation) is a lightweight data-interchange

* format. It is easy for humans to read and write. It is easy for machines

* to parse and generate. It is based on a subset of the JavaScript

* Programming Language, Standard ECMA-262 3rd Edition - December 1999.

* This feature can also be found in  Python. JSON is a text format that is

* completely language independent but uses conventions that are familiar

* to programmers of the C-family of languages, including C, C++, C#, Java,

* JavaScript, Perl, TCL, and many others. These properties make JSON an

* ideal data-interchange language.

*

* This package provides a simple encoder and decoder for JSON notation. It

* is intended for use with client-side Javascript applications that make

* use of HTTPRequest to perform server communication functions - data can

* be encoded into JSON notation for use in a client-side javascript, or

* decoded from incoming Javascript requests. JSON format is native to

* Javascript, and can be directly eval()'ed with no further parsing

* overhead

*

* All strings should be in ASCII or UTF-8 format!
