+	//		This function generates random UUIDs, meaning "version 4" UUIDs.
+	// description:
+	//		A typical generated value would be something like this:
+	//		"3b12f1df-5232-4804-897e-917bf397618a"
+	//		
+	//		For more information about random UUIDs, see sections 4.4 and 
+	//		4.5 of RFC 4122: http://tools.ietf.org/html/rfc4122#section-4.4
+	//		
+	//		This generator function is designed to be small and fast,
+	//		but not necessarily good.
+	//		
+	//		Small: This generator has a small footprint. Once comments are
+	//		stripped, it's only about 25 lines of code, and it doesn't 
+	//		dojo.require() any other modules.
+	//		
+	//		Fast: This generator can generate lots of new UUIDs fairly quickly 
+	//		(at least, more quickly than the other dojo UUID generators).
+	//		
+	//		Not necessarily good: We use Math.random() as our source
+	//		of randomness, which may or may not provide much randomness. 
+	// examples: 
+	//		var string = dojox.uuid.generateRandomUuid();
