evidence-inference: could add NER?

[sg-wbi]

From https://github.com/jayded/evidence-inference/blob/master/annotations/README.md:

Start Evidence: This column represents what index in the text that the “reasoning” from this row starts at (this is inclusive).
End Evidence: This column represents what index in the text that the “reasoning” from this row ends at (this is also inclusive).

This could allow an NER type of task too.
