If this theory defines any Theory.Decoder, which
can translate model data into some theory-specific representation,
this function can be overridden to pre-compute required data
from a model.

Optionally, a set of predicates used by the theory to tell the
PresburgerModelFinder about terms that will be handled
exclusively by this theory.
Optionally, a set of predicates used by the theory to tell the
PresburgerModelFinder about terms that will be handled
exclusively by this theory. If a proof goal in model generation mode
contains an atom p(x), for p in this set,
then the PresburgerModelFinder will ignore x
when assigning concrete values to symbols.
