random_number_generator
model a RandomNumberGenerator (std:25.2.11 [lib.alg.random.shuffle]).
On each invocation, it returns a uniformly distributed integer in
the range [0..n).
The template parameter IntType shall denote some
integer-like value type.
Note: I consider it unfortunate that the C++ Standard uses the name RandomNumberGenerator for something rather specific.
random_number_generator(base_type & rng)Effects: Constructs a
random_number_generator functor with the given uniform
random number generator as the underlying source of random numbers.
result_type operator()(argument_type n)Returns: The value of
uniform_int<base_type>(rng, 0, n-1)().
