/**
* The arrow precision. This counts arrowheads maniacally, wherever they occur in the graphs. The true positives are the
* number of arrowheads in both the true and estimated graphs. Thus, if the true contains X*->Y and estimated graph
* either does not contain an edge from X to Y or else does not contain an arrowhead at X for an edge from X to Y, one
* false positive is counted. Similarly for false negatives.
