/**
 * A random variate generator is used to join a random number
 * generator together with a random number distribution.
 * Boost.Random provides a vast choice of \generators as well
 * as \distributions.
 *
 * The argument for the template parameter Engine shall be of
 * the form U, U&, or U*, where U models a
 * \uniform_random_number_generator.  Then, the member
 * engine_value_type names U (not the pointer or reference to U).
 *
 * Specializations of @c variate_generator satisfy the
 * requirements of CopyConstructible. They also satisfy the
 * requirements of Assignable unless the template parameter
 * Engine is of the form U&.
 *
 * The complexity of all functions specified in this section
 * is constant. No function described in this section except
 * the constructor throws an exception.
