    /**
    * 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!
