-- Schmitty the Solver
--
-- Defines the `Reflectable` class, which is used to provide integration with
-- Agda reflection. To implement the `Reflectable` class, you need to provide
-- conversions from the raw theory to the intended theory.
--
-- Optionally, you may implement the `proofComputation` function, which is used
-- to generate proof objects which compute on closed terms. For an example, see
-- `SMT.Theories.Ints.Reflectable`.
