* 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
* All strings should be in ASCII or UTF-8 format!

* instead of objects in decode().
* - SERVICES_JSON_SUPPRESS_ERRORS: error suppression.
* Values which can't be encoded (e.g. resources)
* appear as NULL instead of throwing errors.
* By default, a deeply-nested resource will
* bubble up with an error, so all return values
* from encode() should be checked with isError()
* - SERVICES_JSON_USE_TO_JSON: call toJSON when serializing objects
* It serializes the return value from the toJSON call rather
* than the object itself, toJSON can return associative arrays,
* strings or numbers, if you return an object, make sure it does
* not have a toJSON method, otherwise an error will occur.

* As per JSON spec if any array key is not an integer

* also try to catch a sparsely populated associative
* array with numeric keys here because some JS engines
* will create an array with empty indexes up to
* max_index which can cause memory issues and because
* the keys, which may be relevant, will be remapped
* As per the ECMA and JSON specification an object may
* have any string as a property. Unfortunately due to
* a hole in the ECMA specification if the key is a
* ECMA reserved word or starts with a digit the
* parameter is only accessible using ECMAScript's
It is recommended that you Edit text format, this type of Fix handles quite a lot in one request
