 This file creates a global JSON object containing two methods: stringify
 and parse.

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

 replacer    an optional parameter that determines how object
 values are stringified for objects. It can be a
 function or an array of strings.

 space       an optional parameter that specifies the indentation
 of nested structures. If it is omitted, the text will
 be packed without extra whitespace. If it is a number,
 it will specify the number of spaces to indent at each
 level. If it is a string (such as '\t' or '&nbsp;'),
 it contains the characters used to indent at each level.

 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 will 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 value

 For example, this would serialize Dates as ISO strings.

 Date.prototype.toJSON = function (key) {
 function f(n) {
 // Format integers to have at least two digits.
 return n < 10 ? '0' + n : n;
 }

 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 the replacer parameter is an array of strings, 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 representations, 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.

 The optional space parameter produces a stringification of the
 value that is filled with line breaks and indentation to make it
 easier to read.

 If the space parameter is a non-empty string, then that string will
 be used for indentation. If the space parameter is a number, then
 the indentation will be that many spaces.

 Example:

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


 text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t');
 // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'

 text = JSON.stringify([new Date()], function (key, value) {
 return this[key] instanceof Date ?
 'Date(' + this[key] + ')' : value;
 });
 // text is '["Date(---current time---)"]'


 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 the 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;
 });

 myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) {
 var d;
 if (typeof value === 'string' &&
 value.slice(0, 5) === 'Date(' &&
 value.slice(-1) === ')') {
 d = new Date(value.slice(5, -1));
 if (d) {
 return d;
 }
 }
 return value;
 });
