virtual void consumeRing(const VarNames &names)
Tell the consumer which ring is being used.

virtual void doneConsuming()
Must be called once after each time beginConsuming has been called.
virtual void beginConsuming()
Tell the consumer to begin consuming an ideal.

TermTranslator handles translation between terms whose exponents are infinite precision integers and ...
Term represents a product of variables which does not include a coefficient.
