-/**
- * 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!
