Property repeats

[cbizon]

Run X-treats->schizophrenia through strider, omnicorp, and ranker, then send to property coalesce.

We find multiple coalsescences on the same exact properties. i.e. sets of two nodes are picked out, and then a different set of 2 nodes is picked out with the same properties.

My current guess is that the omnicorp edges are interfering with the coalescent opportunities, but I have not tested that.

Probably, we should ignore support edges in coalescing.

Confirmed that removing the omnicorp edges from the graph before sending to AC solves this problem.

Omnicorp now happens after AC in aragorn. However, we might still want some logic about which edges to worry about / exclude since operations/workflow may lead to situations in which this re-occurs
