In this ticket: #48
KPs will return to ARAs edges with attributes related to source provenance.

ARAS now need to return this information, along with adding to the edges attributes describing the edge's return from the ARA.

If the ARA adds edges from other sources (such as NGD or other lit co-occurrence or calculated edges), then provenance for these new edges should also be added.

The details of what these properties look like is/will be described in the KP issue linked above.
