The Derivation semiring keeps track of a single path or derivation
that led to the known output. If there are more than one path it discards
in favor the lesser path (based on ord). The main purpose of this semiring
is to track derivations for ViterbiNBestDerivation. If you want to keep all paths,
use MultiDerivation.
Derivation takes a Monoid as an argument that describes how to build up paths or
more complicated structures.

The MultiDerivation semiring keeps track of a all paths or derivations
that led to the known output. This can be useful for debugging output.
Keeping all these paths around can be expensive. MultiDerivation leaves open
the implementation of the internal path monoid for more compact representations.
