Missing test cases for multi-valued reference maps

[chrdebru]

As the title implies, we should have some where multi-valued term maps are used to generate multiple subjects, objects, predicates, ... from one iteration.

As this is about test-cases, I'll assign it to @DylanVanAssche. Please, decide if we go for this now, or we will wait for a future release of test-cases (i.e. working-group label)

@dachafra We need to have an example first to know what the behavior is that we expect, I'm not entirely sure.
How does a multi-value term map look like (with data in and out?)> @chrdebru

I can add test cases for this. I want to clean up and rearrange the test cases anyway.

[DylanVanAssche]

@pmaria That would be great!
