-- | A numeric type to manage engineering units.
--   
--   Provides automatic unit conversion:
--   
--   <pre>
--   &gt; print $ value (1 * h + 1 * min') s        -- Time in seconds of 1 hour + 1 minute.
--   3660.0
--   </pre>
--   
--   Automatic unit reduction:
--   
--   <pre>
--   &gt; print $ value (20 * gpm * 10 * min') gal  -- Note the minutes cancel each other out.
--   200.0
--   </pre>
--   
--   And consistency checking:
--   
--   <pre>
--   &gt; print $ value (22 * mph + 3 gal) mph      -- Note that speed (m/s) is inconsistent with volume (m^3).
--   *** Exception: Incompatible units: [M]/[S] /= [M,M,M]/[]
--   </pre>
--   
--   And defining new units is easy:
--   
--   <pre>
--   -- | Millimeters, a measure of distance, is 1/1000 of a meter.
--   mm :: Value
--   mm = 0.001 * m
--   </pre>
--   
--   <pre>
--   -- | Joules, a measure of energy, is one newton meter.
--   j :: Value
--   j = n * m
--   </pre>
