/**
* This module wraps the incompatible Gecko 1.9.0 (Firefox 3.0) and Gecko 1.9.1
* (Firefox 3.5) JSON APIs, presenting the Gecko 1.9.1 API on both versions,
* for extensions that support multiple versions of Gecko-based applications.
*
* Import this module into your extension to parse and stringify JSON in both
* Firefox 3.0 and 3.5 (and other Gecko-based applications, like Thunderbird)
* without checking the application's version each time.
*
* Note: don't import this into the global namespace! If you do, you'll hork
* native application code that expects the Gecko 1.9.0 API. Instead, import it
* into your own object like this:
*
* let MyExtension = {
* JSON: null,
* ...
* };
* Components.utils.import("chrome://myextension/modules/JSON.js", MyExtension);
* // Now MyExtension.JSON is an object implementing the Gecko 1.9.1 JSON API.
*
* The Gecko 1.9.1 (Firefox 3.5) JSON API is documented in the article:
* https://developer.mozilla.org/En/Using_JSON_in_Firefox
