IEPY runner outputs some facts with no evidence

[francolq]

Specifically, those facts that are seed facts. For instance:

disease,botulism,symptom,paralysis,CAUSES,,,,,1

This behaviour would be correct if we say IEPY must output facts (not necessarily evidence). Seed facts don't need evidence that justify them. However, I think IEPY focus is to find evidence for facts in documents, not facts themselves.
