		//   This function generates random UUIDs, meaning "version 4" UUIDs.
		// description: 
		//   A typical generated value would be something like this:
		//   "3b12f1df-5232-4804-897e-917bf397618a"
		// returnType: The type of object to return. Usually String or dojo.uuid.Uuid

		// examples: 
		//   var string = dojo.uuid.RandomGenerator.generate();
		//   var string = dojo.uuid.RandomGenerator.generate(String);
		//   var uuid   = dojo.uuid.RandomGenerator.generate(dojo.uuid.Uuid);
