-- Tested with: GHC 8.0.1

-- The module defines the 'Parameter' monad transformer that allows representing the model
-- parameters. For example, they can be used when running the Monte-Carlo simulation.
-- 
-- In general, this monad is very useful for representing a computation which is external
-- relative to the model itself.
