Check whether two distributions are equal when neglecting rounding
errors. We do not want to put this into an Eq instance, since
it is not exact equivalence and it seems to be too easy to mix it up
with liftM2 (==) x y.
Probabilistic Functional Programming
The Library allows exact computation with discrete random variables in
terms of their distributions by using a monad. The monad is similar to
the List monad for non-deterministic computations, but extends the
List monad by a measure of probability. Small interface to R plotting.
