typedef _Result result_type
result_type is the return type

  Public Member Functions
unsigned int operator() (unsigned int __limit)
Returns a number less than the argument.
subtractive_rng (unsigned int __seed)
Ctor allowing you to initialize the seed.
subtractive_rng ()
Default ctor; initializes its state with some number you don't see.
