Synopsis:       Log-domain floating point numbers
Description:    This module presents a type for storing numbers
                in the log-domain. The main reason for doing this
                is to prevent underflow when multiplying many
                probabilities as is done in Hidden Markov Models.
                It is also helpful for preventing overflow.

-- Doing it this way uncovers a bug in Cabal-1.2.3.0:
-- "Setup.hs: 'parseField' called on a non-field.  This is a bug."
--Flag hiddenPrim
--    Description: Use GHC 6.10's newly hidden package for GHC.Prim
--    if impl(ghc >= 6.10)
--        Default: true
--    else
--        Default: false
