	// 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
