+	// summary:
+	//	The goal of dojox.flash is to make it easy to extend Flash's capabilities
+	//	into an Ajax/DHTML environment.
+	//  
+	//	dojox.flash provides an easy object for interacting with the Flash plugin. 
+	//	This object provides methods to determine the current version of the Flash
+	//	plugin (dojox.flash.info); write out the necessary markup to 
+	//	dynamically insert a Flash object into the page (dojox.flash.Embed; and 
+	//	do dynamic installation and upgrading of the current Flash plugin in 
+	//	use (dojox.flash.Install). If you want to call methods on the Flash object
+	//	embedded into the page it is your responsibility to use Flash's ExternalInterface
+	//	API and get a reference to the Flash object yourself.
+	//		
+	//	To use dojox.flash, you must first wait until Flash is finished loading 
+	//	and initializing before you attempt communication or interaction. 
+	//	To know when Flash is finished use dojo.connect:
+	//		
+	//	dojo.connect(dojox.flash, "loaded", myInstance, "myCallback");
+	//		
+	//	Then, while the page is still loading provide the file name:
+	//		
+	//	dojox.flash.setSwf(dojo.moduleUrl("dojox", "_storage/storage.swf"));
+	//			
+	//	If no SWF files are specified, then Flash is not initialized.
+	//		
+	//	Your Flash must use Flash's ExternalInterface to expose Flash methods and
+	//	to call JavaScript.
+	//		
+	//	setSwf can take an optional 'visible' attribute to control whether
+	//	the Flash object is visible or not on the page; the default is visible:
+	//		
+	//	dojox.flash.setSwf(dojo.moduleUrl("dojox", "_storage/storage.swf"),
+	//						false);
+	//		
+	//	Once finished, you can query Flash version information:
+	//		
+	//	dojox.flash.info.version
+	//		
+	//	Or can communicate with Flash methods that were exposed:	
+	//
+	//	var f = dojox.flash.get();
+	//	var results = f.sayHello("Some Message");	
+	// 
+	//	Your Flash files should use DojoExternalInterface.as to register methods;
+	//	this file wraps Flash's normal ExternalInterface but correct various
+	//	serialization bugs that ExternalInterface has.
+	//
+	//	Note that dojox.flash is not meant to be a generic Flash embedding
+	//	mechanism; it is as generic as necessary to make Dojo Storage's
+	//	Flash Storage Provider as clean and modular as possible. If you want 
+	//	a generic Flash embed mechanism see SWFObject 
+	//	(http://blog.deconcept.com/swfobject/).
+	//
+	// 	Notes:
+	//	Note that dojox.flash can currently only work with one Flash object
+	//	on the page; it does not yet support multiple Flash objects on
+	//	the same page. 
+	//		
+	//	Your code can detect whether the Flash player is installing or having
+	//	its version revved in two ways. First, if dojox.flash detects that
+	//	Flash installation needs to occur, it sets dojox.flash.info.installing
+	//	to true. Second, you can detect if installation is necessary with the
+	//	following callback:
+	//		
+	//	dojo.connect(dojox.flash, "installing", myInstance, "myCallback");
+	//		
+	//	You can use this callback to delay further actions that might need Flash;
+	//	when installation is finished the full page will be refreshed and the
+	//	user will be placed back on your page with Flash installed.
+	//		
+	//	-------------------
+	//	Todo/Known Issues
+	//	-------------------
+	//	* On Internet Explorer, after doing a basic install, the page is
+	//	not refreshed or does not detect that Flash is now available. The way
+	//	to fix this is to create a custom small Flash file that is pointed to
+	//	during installation; when it is finished loading, it does a callback
+	//	that says that Flash installation is complete on IE, and we can proceed
+	//	to initialize the dojox.flash subsystem.
+	//	* Things aren't super tested for sending complex objects to Flash
+	//	methods, since Dojo Storage only needs strings
+	//
