4/**
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!
