statechum.model.testset.PTA_computePrecisionRecall.crossWith()
Calculates precision/recall when supplied with a specific set of sequences (such as a test set, backed by an FSM). When we record sequences, non-existing transitions at the ends are recorded too, however if we have a long non-existing path, only the first non-existing transition is being recorded. This is in compliance with the training data which only has one non-existing transition at the end of every non-existing path (by construction, we do not build long paths with multiple non-existing transitions). @param pc the set of sequences.
