This PR generalises many results from confluent to commuting relations, and obtains the classical case as a specialisation. We add
HJoinandMHJoin— heterogenous versions ofJoinandMJoin— and associated API for them and related relational constructions.NB: the theorem
confluent_equivalentsis now public, and theTFAEhas been extended with certain other properties which generalise better to the heterogenous case.
