> When there are multiple incoming edges to the tezprocessor we'll need to be able to tell which alias or tag they belong to.
> In the map case:
> - Potentially multiple MRInputs. Need to map those to aliases/operators
> In the reduce case:
> - Each tag will be represented by a logical input. We need to know which table each input belongs to.
> NO PRECOMMIT TESTS (this is wip for the tez branch)
