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 while maintaining
        the same performance. Disable only if your compiler doesn't
        support FFI.
