Public Domain.

NO WARRANTY EXPRESSED OR IMPLIED. USE AT YOUR OWN RISK.

See http://www.JSON.org/js.html

This file creates a global JSON object containing three methods: stringify,
parse, and quote.

JSON.stringify(value, replacer)
value       any JavaScript value, usually an object or array.

replacer    an optional parameter that determines how object
values are stringified for objects without a toJSON
method. It can be a function or an array.

This method produces a JSON text from a JavaScript value.

When an object value is found, if the object contains a toJSON
method, its toJSON method with be called and the result will be
stringified. A toJSON method does not serialize: it returns the
value represented by the name/value pair that should be serialized,
or undefined if nothing should be serialized. The toJSON method will
be passed the key associated with the value, and this will be bound
to the object holding the key.

This is the toJSON method added to Dates:

function toJSON(key) {
return this.getUTCFullYear()   + '-' +
f(this.getUTCMonth() + 1) + '-' +
f(this.getUTCDate())      + 'T' +
f(this.getUTCHours())     + ':' +
f(this.getUTCMinutes())   + ':' +
f(this.getUTCSeconds())   + 'Z';
}

You can provide an optional replacer method. It will be passed the
key and value of each member, with this bound to the containing
object. The value that is returned from your method will be
serialized. If your method returns undefined, then the member will
be excluded from the serialization.

If no replacer parameter is provided, then a default replacer
will be used:

function replacer(key, value) {
return Object.hasOwnProperty.call(this, key) ?
value : undefined;
}

The default replacer is passed the key and value for each item in
the structure. It excludes inherited members.

If the replacer parameter is an array, then it will be used to
select the members to be serialized. It filters the results such
that only members with keys listed in the replacer array are
stringified.

Values that do not have JSON representaions, such as undefined or
functions, will not be serialized. Such values in objects will be
dropped; in arrays they will be replaced with null. You can use
a replacer function to replace those with JSON values.
JSON.stringify(undefined) returns undefined.

Example:

var text = JSON.stringify(['e', {pluribus: 'unum'}]);
// text is '["e",{"pluribus":"unum"}]'

JSON.parse(text, reviver)
This method parses a JSON text to produce an object or array.
It can throw a SyntaxError exception.

The optional reviver parameter is a function that can filter and
transform the results. It receives each of the keys and values, and
its return value is used instead of the original value. If it
returns what it received, then structure is not modified. If it
returns undefined then the member is deleted.

Example:

// Parse the text. Values that look like ISO date strings will
// be converted to Date objects.

myData = JSON.parse(text, function (key, value) {
var a;
if (typeof value === 'string') {
a = /^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/
.exec(value);
if (a) {
return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],
+a[5], +a[6]));
}
}
return value;
});

JSON.quote(text)
This method wraps a string in quotes, escaping some characters
as needed.

redistribute.
