+HISTORY:
+6/5/06 	- Initial Release
+5/22/08 - Updated code to run faster, removed randrange(min,max) in favor of
+          a simpler rand(max) function. Reduced overhead by using getTime() 
+          method of date class (suggestion by James Hall).
+9/5/08	- Fixed a bug with rand(max) and additional efficiencies pointed out 
+	  by Robert Kieffer http://broofa.com/
+ 
+KNOWN ISSUES:
+- Still no way to get MAC address in JavaScript
+- Research into other versions of UUID show promising possibilities 
+  (more research needed)
+- Documentation needs improvement
