			// checkDojoRequirePlugin inspects all of the modules demanded by a dojo/require!<module-list> dependency
			// to see if they have arrived. The loader does not release *any* of these modules to be instantiated
			// until *all* of these modules are on board, thereby preventing the evaluation of a module with dojo.require's
			// that reference modules that are not available.
			//
			// The algorithm works by traversing the dependency graphs (remember, there can be cycles so they are not trees)
			// of each module in the dojoRequireModuleStack array (which contains the list of modules demanded by dojo/require!).
			// The moment a single module is discovered that is missing, the algorithm gives up and indicates that not all
			// modules are on board. dojo/loadInit! and dojo/require! are ignored because there dependencies are inserted
			// directly in dojoRequireModuleStack. For example, if "your/module" module depends on "dojo/require!my/module", then
			// *both* "dojo/require!my/module" and "my/module" will be in dojoRequireModuleStack. Obviously, if "my/module"
			// is on board, then "dojo/require!my/module" is also satisfied, so the algorithm doesn't check for "dojo/require!my/module".
			//
			// Note: inserting a dojo/require!<some-module-list> dependency in the dojoRequireModuleStack achieves nothing
			// with the current algorithm; however, having such modules present makes it possible to optimize the algorithm
			//
			// Note: prior versions of this algorithm had an optimization that signaled loaded on dojo/require! dependencies

		//
		// description:
		//		Modules are loaded via dojo.require by using one of two loaders: the normal loader
		//		and the xdomain loader. The xdomain loader is used when dojo was built with a
		//		custom build that specified loader=xdomain and the module lives on a modulePath
		//		that is a whole URL, with protocol and a domain. The versions of Dojo that are on
		//		the Google and AOL CDNs use the xdomain loader.
		//
		//		If the module is loaded via the xdomain loader, it is an asynchronous load, since
		//		the module is added via a dynamically created script tag. This
		//		means that dojo.require() can return before the module has loaded. However, this
		//		should only happen in the case where you do dojo.require calls in the top-level
		//		HTML page, or if you purposely avoid the loader checking for dojo.require
		//		dependencies in your module by using a syntax like dojo["require"] to load the module.
		//
		//		Sometimes it is useful to not have the loader detect the dojo.require calls in the
		//		module so that you can dynamically load the modules as a result of an action on the
		//		page, instead of right at module load time.
		//
		//		Also, for script blocks in an HTML page, the loader does not pre-process them, so
		//		it does not know to download the modules before the dojo.require calls occur.
		//
		//		So, in those two cases, when you want on-the-fly module loading or for script blocks
		//		in the HTML page, special care must be taken if the dojo.required code is loaded
		//		asynchronously. To make sure you can execute code that depends on the dojo.required
		//		modules, be sure to add the code that depends on the modules in a dojo.addOnLoad()
		//		callback. dojo.addOnLoad waits for all outstanding modules to finish loading before
		//		executing.
		//
		//		This type of syntax works with both xdomain and normal loaders, so it is good
		//		practice to always use this idiom for on-the-fly code loading and in HTML script
		//		blocks. If at some point you change loaders and where the code is loaded from,
		//		it will all still work.
		//
		//		More on how dojo.require
		//		`dojo.require("A.B")` first checks to see if symbol A.B is
		//		defined. If it is, it is simply returned (nothing to do).
		//
		//		If it is not defined, it will look for `A/B.js` in the script root
		//		directory.
		//
		//		`dojo.require` throws an exception if it cannot find a file
		//		to load, or if the symbol `A.B` is not defined after loading.
		//
		//		It returns the object `A.B`, but note the caveats above about on-the-fly loading and
		//		HTML script blocks when the xdomain loader is loading a module.
		//
		//		`dojo.require()` does nothing about importing symbols into
		//		the current namespace.	It is presumed that the caller will
		//		take care of that.
		//
		// example:
		//		To use dojo.require in conjunction with dojo.ready:
		//
		//		|	dojo.require("foo");
		//		|	dojo.require("bar");
		//		|	dojo.addOnLoad(function(){
		//		|		//you can now safely do something with foo and bar
		//		|	});
		//
		// example:
		//		For example, to import all symbols into a local block, you might write:
		//
		//		|	with (dojo.require("A.B")) {
		//		|		...
		//		|	}
		//
		//		And to import just the leaf symbol to a local variable:
		//
		//		|	var B = dojo.require("A.B");
		//		|	...
		//
		// returns:
		//		the required namespace object

		// example:
		//		If your dojo.js is located at this location in the web root:
		//	|	/myapp/js/dojo/dojo/dojo.js
		//		and your modules are located at:
		//	|	/myapp/js/foo/bar.js

		//	|	dojo.registerModulePath("foo", "../../foo");
		//		At which point you can then use dojo.require() to load the
		//		modules (assuming they provide() the same things which are
		//		required). The full code might be:
		//	|	<script type="text/javascript"
		//	|		src="/myapp/js/dojo/dojo/dojo.js"></script>
		//	|	<script type="text/javascript">
		//	|		dojo.registerModulePath("foo", "../../foo");
