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.

Flag useFFI
    Default:     True
    Description: Use FFI to link C's log1p. Improves accuracy and
                 same performance. Disable only if your compiler
                 doesn't support FFI.
