Still needs an example.

+StreamSelect indicates the offset in the random number sequence to begin sampling, and MGSeed and LCGSeed can be used to modify the seed values used by the RandomStream class.

+=== HyperExponentialStream
+
+The HyperExponential class returns a hyper-exponential distribution of random numbers, with mean mean and standard deviation sd.

+
+=== NormalStream
+
+NormalStream returns a normal distribution of random numbers, with mean mean and standard deviation sd. operator() uses the polar method due to link:http://www.amazon.com/Art-Computer-Programming-Volume-Seminumerical/dp/0201896842[Box, Muller, and Marsaglia.]

+
+=== Draw
+
+The Draw class is the exception to the inheritance rule, instead using RandomStream through delegation (for historical reasons). This returns true with the probability prob, and false otherwise.
