+ * 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!

+ *
+ * 2007-12-13: Cleaned up for initial public release
+ * 2008-05-10: Moved all helper functions into a class.  API access unchanged.
+ * 2009-06-23: Created abstraction of hash() routine
+ * 2009-07-23: Added detection of 32 vs 64bit platform, and patches.
+ *             Ability to define "_NANO_SHA2_UPPER" to yeild upper case hashes.
+ * 2009-08-01: Added ability to attempt to use mhash() prior to running pure
+ *             php code.
+ *
+ * NOTE: Some sporadic versions of PHP do not handle integer overflows the
+ *       same as the majority of builds.  If you get hash results of:
+ *        7fffffff7fffffff7fffffff7fffffff7fffffff7fffffff7fffffff7fffffff
+ *
+ *       If you do not have permissions to change PHP versions (if you did
+ *       you'd probably upgrade to PHP 5 anyway) it is advised you install a
+ *       module that will allow you to use their hashing routines, examples are:
+ *       - mhash module : http://ca3.php.net/mhash
+ *       - Suhosin : http://www.hardened-php.net/suhosin/
+ *
+ *       If you install the Suhosin module, this script will transparently
+ *       use their routine and define the PHP routine as _nano_sha256().
+ *
+ *       If the mhash module is present, and $ignore_php5_hash = false the
+ *       script will attempt to use the output from mhash prior to running
+ *       the PHP code.
