Random number generation based on modeling random variables in two
complementary ways: first, by the parameters of standard mathematical
distributions and, second, by an abstract type ('RVar') which can be composed
and manipulated monadically and sampled in either monadic or "pure" styles.
The primary purpose of this library is to support defining and sampling a wide
variety of high quality random variables. Quality is prioritized over speed,
but performance is an important goal too.
In my testing, I have found it capable of speed comparable to other Haskell
libraries, but still a fair bit slower than straight C implementations of the
