-/**
-* 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!
-*
-* PHP versions 4 and 5
