-- | Log-domain floating point numbers
--   
--   This module presents a class 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.
