    json_parse.js

Public Domain.

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

This file creates a json_parse function.
    During create you can (optionally) specify some behavioural switches

require('json-bigint')(options)

The optional options parameter holds switches that drive certain
            aspects of the parsing process:
            * options.strict = true will warn about duplicate-key usage in the json.
              The default (strict = false) will silently ignore those and overwrite
              values for keys that are in duplicate use.

The resulting function follows this signature:
        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;
            });
