-- * Implementing a custom Formatter

-- A formatter is a set of actions.  Each action is evaluated when a certain
-- situation is encountered during a test run.
--
-- Actions live in the `FormatM` monad.  It provides access to the runner state
-- and primitives for appending to the generated report.
