	5	* Converts to and from JSON format.
	6	*
	7	* JSON (JavaScript Object Notation) is a lightweight data-interchange
	8	* format. It is easy for humans to read and write. It is easy for machines
	9	* to parse and generate. It is based on a subset of the JavaScript
	10	* Programming Language, Standard ECMA-262 3rd Edition - December 1999.
	11	* This feature can also be found in Python. JSON is a text format that is
	12	* completely language independent but uses conventions that are familiar
	13	* to programmers of the C-family of languages, including C, C++, C#, Java,
	14	* JavaScript, Perl, TCL, and many others. These properties make JSON an
	15	* ideal data-interchange language.
	16	*
	17	* This package provides a simple encoder and decoder for JSON notation. It
	18	* is intended for use with client-side Javascript applications that make
	19	* use of HTTPRequest to perform server communication functions - data can
	20	* be encoded into JSON notation for use in a client-side javascript, or
	21	* decoded from incoming Javascript requests. JSON format is native to
	22	* Javascript, and can be directly eval()'ed with no further parsing
	23	* overhead
	24	*
	25	* All strings should be in ASCII or UTF-8 format!
