		//	omitModuleCheck:
		//		if `true`, omitModuleCheck skips the step of ensuring that the
		//		loaded file actually defines the symbol it is referenced by.
		//		For example if it called as `dojo._loadModule("a.b.c")` and the
		//		file located at `a/b/c.js` does not define an object `a.b.c`,
		//		and exception will be throws whereas no exception is raised
		//		when called as `dojo._loadModule("a.b.c", true)`
		//	description:
		//		`dojo._loadModule("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._loadModule` throws an excpetion 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`.
		//	
		//		`dojo._loadModule()` does nothing about importing symbols into
		//		the current namespace.  It is presumed that the caller will
		//		take care of that. For example, to import all symbols into a
		//		local block, you might write:
		//	
		//		|	with (dojo._loadModule("A.B")) {
		//		|		...
		//		|	}
		//	
		//		And to import just the leaf symbol to a local variable:
		//	
		//		|	var B = dojo._loadModule("A.B");
		//	   	|	...
		//	returns: the required namespace object

		//		`dojo.provide("dojo.foo");` before any calls to
		//		`dojo.require()` are made.
		//	description:
		//		Each javascript source file is called a resource.  When a
		//		resource is loaded by the browser, `dojo.provide()` registers
		//		that it has been loaded.
		//	
		//		For backwards compatibility reasons, in addition to registering
		//		the resource, `dojo.provide()` also ensures that the javascript
		//		object for the module exists.  For example,
		//		`dojo.provide("dojox.data.FlickrStore")`, in addition to
		//		registering that `FlickrStore.js` is a resource for the
		//		`dojox.data` module, will ensure that the `dojox.data`
		//		javascript object exists, so that calls like 
		//		`dojo.data.foo = function(){ ... }` don't fail.
		//
		//		In the case of a build where multiple javascript source files
		//		are combined into one bigger file (similar to a .lib or .jar
		//		file), that file may contain multiple dojo.provide() calls, to
		//		note that it includes multiple resources.

		//		This method takes a "map" of arrays which one can use to
		//		optionally load dojo modules. The map is indexed by the
		//		possible dojo.name_ values, with two additional values:
		//		"default" and "common". The items in the "default" array will
		//		be loaded if none of the other items have been choosen based on
		//		dojo.name_, set by your host environment. The items in the
		//		"common" array will *always* be loaded, regardless of which
		//		list is chosen.
		//	example:
		//		|	dojo.platformRequire({
		//		|		browser: [
		//		|			"foo.sample", // simple module
		//		|			"foo.test",
		//		|			["foo.bar.baz", true] // skip object check in _loadModule

		//		An unregistered module is given the default path of ../[module],
		//		relative to Dojo root. For example, module acme is mapped to
		//		../acme.  If you want to use a different module name, use
		//		dojo.registerModulePath. 
		//	example:
		//		If your dojo.js is located at this location in the web root:
		//	|	/myapp/js/dojo/dojo/dojo.js

		//	|	/myapp/js/foo/bar.js
		//	|	/myapp/js/foo/baz.js
		//	|	/myapp/js/foo/thud/xyzzy.js
		//		Your application can tell Dojo to locate the "foo" namespace by calling:
		//	|	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>

		//	|		dojo.registerModulePath("foo", "../../foo");

		//		the locale to load (optional)  By default, the browser's user
		//		locale as defined by dojo.locale
		// availableFlatLocales:

		// description:
		//		Load translated resource bundles provided underneath the "nls"
		//		directory within a package.  Translated resources may be located in
		//		different packages throughout the source tree.  For example, a
		//		particular widget may define one or more resource bundles,
		//		structured in a program as follows, where moduleName is
		//		mycode.mywidget and bundleNames available include bundleone and
		//		bundletwo:
		//
		//	|		...
		//	|		mycode/
		//	|		 mywidget/
		//	|		  nls/
		//	|		   bundleone.js (the fallback translation, English in this example)
		//	|		   bundletwo.js (also a fallback translation)
		//	|		   de/
		//	|		    bundleone.js
		//	|		    bundletwo.js
		//	|		   de-at/
		//	|		    bundleone.js
		//	|		   en/
		//	|		    (empty; use the fallback translation)
		//	|		   en-us/
		//	|		    bundleone.js
		//	|		   en-gb/
		//	|		    bundleone.js
		//	|		   es/
		//	|		    bundleone.js
		//	|		    bundletwo.js
		//	|		  ...etc
		//	|		...
		//
		//		Each directory is named for a locale as specified by RFC 3066,
		//		(http://www.ietf.org/rfc/rfc3066.txt), normalized in lowercase.
		//		Note that the two bundles in the example do not define all the
		//		same variants.  For a given locale, bundles will be loaded for
		//		that locale and all more general locales above it, including a
		//		fallback at the root directory.  For example, a declaration for
		//		the "de-at" locale will first load `nls/de-at/bundleone.js`,
		//		then `nls/de/bundleone.js` and finally `nls/bundleone.js`.  The
		//		data will be flattened into a single Object so that lookups
		//		will follow this cascading pattern.  An optional build step can
		//		preload the bundles to avoid data redundancy and the multiple
		//		network hits normally required to load these resources.
