/*=====
dojo.connect = function(obj, event, context, method, dontFix){
	// summary:
	//		`dojo.connect` is the core event handling and delegation method in
	//		Dojo. It allows one function to "listen in" on the execution of
	//		any other, triggering the second whenever the first is called. Many
	//		listeners may be attached to a function, and source functions may
	//		be either regular function calls or DOM events.
	//
	// description:
	//		Connects listeners to actions, so that after event fires, a
	//		listener is called with the same arguments passed to the original
	//		function.
	//
	//		Since `dojo.connect` allows the source of events to be either a
	//		"regular" JavaScript function or a DOM event, it provides a uniform
	//		interface for listening to all the types of events that an
	//		application is likely to deal with though a single, unified
	//		interface. DOM programmers may want to think of it as
	//		"addEventListener for everything and anything".
	//
	//		When setting up a connection, the `event` parameter must be a
	//		string that is the name of the method/event to be listened for. If
	//		`obj` is null, `kernel.global` is assumed, meaning that connections
	//		to global methods are supported but also that you may inadvertently
	//		connect to a global by passing an incorrect object name or invalid
	//		reference.
	//
	//		`dojo.connect` generally is forgiving. If you pass the name of a
	//		function or method that does not yet exist on `obj`, connect will
	//		not fail, but will instead set up a stub method. Similarly, null
	//		arguments may simply be omitted such that fewer than 4 arguments
	//		may be required to set up a connection See the examples for details.
	//
	//		The return value is a handle that is needed to
	//		remove this connection with `dojo.disconnect`.
	//
	// obj: Object|null:
	//		The source object for the event function.
	//		Defaults to `kernel.global` if null.
	//		If obj is a DOM node, the connection is delegated
	//		to the DOM event manager (unless dontFix is true).
	//
	// event: String:
	//		String name of the event function in obj.
	//		I.e. identifies a property `obj[event]`.
	//
	// context: Object|null
	//		The object that method will receive as "this".
	//
	//		If context is null and method is a function, then method
	//		inherits the context of event.
	//
	//		If method is a string then context must be the source
	//		object object for method (context[method]). If context is null,
	//		kernel.global is used.
	//
	// method: String|Function:
	//		A function reference, or name of a function in context.
	//		The function identified by method fires after event does.
	//		method receives the same arguments as the event.
	//		See context argument comments for information on method's scope.
	//
	// dontFix: Boolean?
	//		If obj is a DOM node, set dontFix to true to prevent delegation
	//		of this connection to the DOM event manager.
	//
	// example:
	//		When obj.onchange(), do ui.update():
	//	|	dojo.connect(obj, "onchange", ui, "update");
	//	|	dojo.connect(obj, "onchange", ui, ui.update); // same
	//
	// example:
	//		Using return value for disconnect:
	//	|	var link = dojo.connect(obj, "onchange", ui, "update");
	//	|	...
	//	|	dojo.disconnect(link);
	//
	// example:
	//		When onglobalevent executes, watcher.handler is invoked:
	//	|	dojo.connect(null, "onglobalevent", watcher, "handler");
	//
	// example:
	//		When ob.onCustomEvent executes, customEventHandler is invoked:
	//	|	dojo.connect(ob, "onCustomEvent", null, "customEventHandler");
	//	|	dojo.connect(ob, "onCustomEvent", "customEventHandler"); // same
	//
	// example:
	//		When ob.onCustomEvent executes, customEventHandler is invoked
	//		with the same scope (this):
	//	|	dojo.connect(ob, "onCustomEvent", null, customEventHandler);
	//	|	dojo.connect(ob, "onCustomEvent", customEventHandler); // same
	//
	// example:
	//		When globalEvent executes, globalHandler is invoked
	//		with the same scope (this):
	//	|	dojo.connect(null, "globalEvent", null, globalHandler);
	//	|	dojo.connect("globalEvent", globalHandler); // same
