+       // 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,

+       //              
+       //              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
