	//		the original function is reached, at which point the underlying
	//		function (func) is called in the scope thisObj with all of the
	//		accumulated arguments (plus any extras) in positional order.
	// examples:

	//					dojo.debug.apply(dojo, arguments);

	//			tmp("blah", "this is superfluous");
	//			// debugs: "arg one thinger blah this is superfluous"
	//			tmp("blah");
	//			// debugs: "arg one thinger blah"
	//			tmp();
	//			// returns a function exactly like tmp that expects one argument
	//
	//		other intermittent functions could be created until the 3
	//		positional arguments are filled:
	//
	//			tmp = dojo.lang.curry(foo, foo.bar, "arg one");
	//			tmp2 = tmp("arg two");
	//			tmp2("blah blah");
	//			// debugs: "arg one arg two blah blah"
	//			tmp2("oy");
	//			// debugs: "arg one arg two oy"
	//
	//		curry() can also be used to call the function if enough arguments
	//		are passed in the initial invocation:
	//
	//			dojo.lang.curry(foo, foo.bar, "one", "two", "three", "four");
	//			// debugs: "one two three four"

/*		This is the dojo logging facility, which is imported from nWidgets
		(written by Alex Russell, CLA on file), which is patterned on the
		Python logging module, which in turn has been heavily influenced by
		log4j (execpt with some more pythonic choices, which we adopt as well).

		While the dojo logging facilities do provide a set of familiar
		interfaces, many of the details are changed to reflect the constraints
		of the browser environment. Mainly, file and syslog-style logging
		facilites are not provided, with HTTP POST and GET requests being the
		only ways of getting data from the browser back to a server. Minimal
		support for this (and XML serialization of logs) is provided, but may
		not be of practical use in a deployment environment.

		The Dojo logging classes are agnostic of any environment, and while
		default loggers are provided for browser-based interpreter
		environments, this file and the classes it define are explicitly
		designed to be portable to command-line interpreters and other
		ECMA-262v3 envrionments.

	the logger needs to accomidate:
		log "levels"
		type identifiers
		file?
		message
		tic/toc?

	The logger should ALWAYS record:
		time/date logged
		message
		type
		level

 *		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.
 *
 *	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.

		//	DETECT that you've moved backwards by inspecting window.location.
		//	Unless there is some other means of locating.
		//	FIXME: perhaps we can poll on history.length?
		//	Safari 2.0.3+ (and probably 1.3.2+):
		//	works fine, except when changeUrl is used. When changeUrl is used,
		//	Safari jumps all the way back to whatever page was shown before
		//	the page that uses dojo.undo.browser support.
		//	IE 5.5 SP2:
		//	back button behavior is macro. It does not move back to the
		//	previous hash value, but to the last full page load. This suggests
		//	that the iframe is the correct way to capture the back button in
		//	these cases.
		//	Don't test this page using local disk for MSIE. MSIE will not create 
		//	a history list for iframe_history.html if served from a file: URL. 
		//	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:
		//	same behavior as IE 5.5 SP2
		//	Firefox 1.0+:
		//	the back button will return us to the previous hash on the same
		//	page, thereby not requiring an iframe hack, although we do then

dojo.Deferred = function(/*Function?*/ canceller){
	/*
	NOTE: this namespace and documentation are imported wholesale 
		from MochiKit

	Encapsulates a sequence of callbacks in response to a value that
	may not yet be available.  This is modeled after the Deferred class
	from Twisted <http://twistedmatrix.com>.

	Why do we want this?  JavaScript has no threads, and even if it did,
	threads are hard.  Deferreds are a way of abstracting non-blocking
	events, such as the final response to an XMLHttpRequest.

	The sequence of callbacks is internally represented as a list
	of 2-tuples containing the callback/errback pair.  For example,
	the following call sequence::

		var d = new Deferred();
		d.addCallback(myCallback);
		d.addErrback(myErrback);
		d.addBoth(myBoth);
		d.addCallbacks(myCallback, myErrback);

	is translated into a Deferred with the following internal
	representation::

		[
			[myCallback, null],
			[null, myErrback],
			[myBoth, myBoth],
			[myCallback, myErrback]
		]

	The Deferred also keeps track of its current status (fired).
	Its status may be one of three things:

		-1: no value yet (initial condition)
		0: success
		1: error

	A Deferred will be in the error state if one of the following
	three conditions are met:

		1. The result given to callback or errback is "instanceof" Error
		2. The previous callback or errback raised an exception while
		   executing
		3. The previous callback or errback returned a value "instanceof"
			Error

	Otherwise, the Deferred will be in the success state.  The state of
	the Deferred determines the next element in the callback sequence to
	run.

	When a callback or errback occurs with the example deferred chain,
	something equivalent to the following will happen (imagine that
	exceptions are caught and returned)::

		// d.callback(result) or d.errback(result)
		if(!(result instanceof Error)){
			result = myCallback(result);
		}
		if(result instanceof Error){
			result = myErrback(result);
		}
		result = myBoth(result);
		if(result instanceof Error){
			result = myErrback(result);
		}else{
			result = myCallback(result);
		}

	The result is then stored away in case another step is added to the
	callback sequence.	Since the Deferred already has a value available,
	any new callbacks added will be called immediately.

	There are two other "advanced" details about this implementation that
	are useful:

	Callbacks are allowed to return Deferred instances themselves, so you
	can build complicated sequences of events with ease.

	The creator of the Deferred may specify a canceller.  The canceller
	is a function that will be called if Deferred.cancel is called before
	the Deferred fires.	 You can use this to implement clean aborting of
	an XMLHttpRequest, etc.	 Note that cancel will fire the deferred with
	a CancelledError (unless your canceller returns another kind of
	error), so the errbacks should be prepared to handle that error for
	cancellable Deferreds.

// summary:

//		HtmlDragAndDrop.js, which will be automatically included should you
//		.
//
//		In addition to the various actor classes, a global manager will be

//
// 		The 3 object types involved in any Drag and Drop operation are:
//			* DragSource
//				This is the item that can be selected for dragging. Drag
//				sources can have "types" to help mediate whether or not various
//				DropTargets will accept (or reject them). Most dragging actions
//				are handled by the DragObject which the DragSource generates
//				from its onDragStart method.
//			* DragObject
//				This, along with the manger, does most of the hard work of DnD.
//				Implementations may rely on DragObject instances to implement
//				"shadowing", "movement", or other kinds of DnD variations that
//				affect the visual representation of the drag operation.
//			* DropTarget
//				Represents some section of the screen that can accept drag
//				and drop events. DropTargets keep a list of accepted types
//				which is checked agains the types of the respective DragSource
//				objects that pass over it. DropTargets may implement behaviors
//				that respond to drop events to take application-level actions.

		//		to understand the process by which widgets are instantiated, it

		//		only be done as a last resort.
		//
		//		Below is a list of the methods that are called, in the order
		//		they are fired, along with notes about what they do and if/when
		//		you should over-ride them in your widget:
		//			
		//			mixInProperties:
		//				takes the args and does lightweight type introspection
		//				on pre-existing object properties to initialize widget
		//				values by casting the values that are passed in args
		//			postMixInProperties:
		//				a stub function that you can over-ride to modify
		//				variables that may have been naively assigned by
		//				mixInProperties
		//			# widget is added to manager object here
		//			buildRendering
		//				subclasses use this method to handle all UI initialization
		//			initialize:
		//				a stub function that you can over-ride.
		//			postInitialize:
		//				a stub function that you can over-ride.
		//			postCreate
		//				a stub function that you can over-ride to modify take
		//				actions once the widget has been placed in the UI
		//
		//		all of these functions are passed the same arguments as are
		//		passed to 'create'
