Summarize ECC table

[proost]

"It might be better to reformat the cluster/neighborhood similarity table to show OrthoFinder and MCL-based ECC values as two separate columns for each pair that is compared. In this way, the table would be shorter and you would be able to compare these two values easier. "

Would need to be a generic implementation, as there might be one or more types of gene families. (For the open-source, deploy your own CoNekT, aspect I can't hard-code quick fixes) Not sure yet how that could/should work.
