/**
 * requireLocalization() is for loading translated bundles provided within a package in the namespace.
 * Contents are typically strings, but may be any name/value pair, represented in JSON format.
 * A bundle is structured in a program as follows, where modulename is mycode.mywidget and
 * bundlename is mybundle:
 *
 * mycode/
 *  mywidget/
 *   nls/
 *    mybundle.js (the fallback translation, English in this example)
 *    de/
 *     mybundle.js
 *    de-at/
 *     mybundle.js
 *    en/
 *     (empty; use the fallback translation)
 *    en-us/
 *     mybundle.js
 *    en-gb/
 *     mybundle.js
 *    es/
 *     mybundle.js
 *   ...etc
 *
 * Each directory is named for a locale as specified by RFC 3066, (http://www.ietf.org/rfc/rfc3066.txt),
 * normalized in lowercase.
 *
 * For a given locale, bundles will be loaded for that locale and all less-specific locales above it, as well
 * as a fallback at the root.  For example, a search for the "de-at" locale will first load nls/de-at/mybundle.js,
 * then nls/de/mybundle.js and finally nls/mybundle.js.  Lookups will traverse the locales in this same order
 * and flatten all the values into a JS object (see dojo.i18n.getLocalization).  A build step can preload the
 * bundles to avoid data redundancy and extra network hits.
 *
 * @param modulename package in which the bundle is found
 * @param bundlename bundle name, typically the filename without the '.js' suffix
 * @param locale the locale to load (optional)  By default, the browser's user locale as defined

/******************************************************************************
 *	Notes about dojo.io design:
 *	
 *	The dojo.io.* package has the unenviable task of making a lot of different
 *	types of I/O feel natural, despite a universal lack of good (or even
 *	reasonable!) I/O capability in the host environment. So lets pin this down
 *	a little bit further.
 *
 *	Rhino:
 *		perhaps the best situation anywhere. Access to Java classes allows you
 *		to do anything one might want in terms of I/O, both synchronously and
 *		async. Can open TCP sockets and perform low-latency client/server
 *		interactions. HTTP transport is available through Java HTTP client and
 *		server classes. Wish it were always this easy.
 *
 *	xpcshell:
 *		XPCOM for I/O. A cluster-fuck to be sure.
 *
 *	spidermonkey:
 *		S.O.L.
 *
 *	Browsers:
 *		Browsers generally do not provide any useable filesystem access. We are
 *		therefore limited to HTTP for moving information to and from Dojo
 *		instances living in a browser.
 *
 *		XMLHTTP:
 *			Sync or async, allows reading of arbitrary text files (including
 *			JS, which can then be eval()'d), writing requires server
 *			cooperation and is limited to HTTP mechanisms (POST and GET).
 *
 *		<iframe> hacks:
 *			iframe document hacks allow browsers to communicate asynchronously
 *			with a server via HTTP POST and GET operations. With significant
 *			effort and server cooperation, low-latency data transit between
 *			client and server can be acheived via iframe mechanisms (repubsub).
 *
 *		SVG:
 *			Adobe's SVG viewer implements helpful primitives for XML-based
 *			requests, but receipt of arbitrary text data seems unlikely w/o
 *			<![CDATA[]]> sections.
 *
 *
 *	A discussion between Dylan, Mark, Tom, and Alex helped to lay down a lot
 *	the IO API interface. A transcript of it can be found at:
 *		http://dojotoolkit.org/viewcvs/viewcvs.py/documents/irc/irc_io_api_log.txt?rev=307&view=auto
 *	
 *	Also referenced in the design of the API was the DOM 3 L&S spec:
 *		http://www.w3.org/TR/2004/REC-DOM-Level-3-LS-20040407/load-save.html

 *	Don't test this page using local disk for MSIE. MSIE will not create

 *	The XML served back from the XHR tests will also not be properly 
 *	created if served from local disk. Serve the test pages from a web 
 *	server to test in that browser.
 *  IE 6.0:

	 *   passed as the first and only argument to this callback.
	 * - To support getting forward button notifications, the object argument should implement a
	 *   function called either "forward", "forwardButton", or "handle". The string "forward" will be
	 *   passed as the first and only argument to this callback.
	 * - If you want the browser location string to change, define "changeUrl" on the object. If the
	 *   value of "changeUrl" is true, then a unique number will be appended to the URL as a fragment
	 *   identifier (http://some.domain.com/path#uniquenumber). If it is any other value that does
	 *   not evaluate to false, that value will be used as the fragment identifier. For example,
	 *   if changeUrl: 'page1', then the URL will look like: http://some.domain.com/path#page1

	 * Full example:
	 *

/*
 * Creates a constructor: inherit and extend
 *
 * - inherits from "superclass(es)" 
 *
 *   "superclass" argument may be a Function, or an array of 
 *   Functions. 
 *
 *   If "superclass" is an array, the first element is used 
 *   as the prototypical ancestor and any following Functions 
 *   become mixin ancestors. 
 * 
 *   All "superclass(es)" must be Functions (not mere Objects).
 *
 *   Using mixin ancestors provides a type of multiple
 *   inheritance. Mixin ancestors prototypical 
 *   properties are copied to the subclass, and any 
 *   inializater/constructor is invoked. 
 *
 * - "props" are copied to the constructor prototype
 *
 * - name of the class ("className" argument) is stored in 
 *   "declaredClass" property
 * 
 * - An initializer function can be specified in the "init" 
 *   argument, or by including a function called "initializer" 
 *   in "props".
 * 
 * - Superclass methods (inherited methods) can be invoked using "inherited" method:
 *
 * this.inherited(<method name>[, <argument array>]);
 * 
 * - inherited will continue up the prototype chain until it finds an implementation of method
 * - nested calls to inherited are supported (i.e. inherited method "A" can succesfully call inherited("A"), and so on)
 *
 * Aliased as "dojo.declare"
 *
 * Usage:
 *
 * dojo.declare("my.classes.bar", my.classes.foo, {
 *	initializer: function() {
 *		this.myComplicatedObject = new ReallyComplicatedObject(); 
 *	},
 *	someValue: 2,
 *	aMethod: function() { doStuff(); }
 * });
