13. def getFeatureMatcher(feature: String, startFromSourceNode: Boolean, graph: Graph): Option[FeatureMatcher[NodePairInstance]]

    This method essentially goes backward from a FeatureExtractor.

    This method essentially goes backward from a FeatureExtractor. FeatureExtractor.extractFeatures lets you take a subgraph and get features out. This method takes features in, then lets you filter the graph to only subgraphs that would have generated this feature.

    The default implementation here is to return None, and we will override it in the few cases where I've put in the effort to make feature matching work.

    I originally had this as part of FeatureExtractor, with this overriding a base method there. But, I need to have startFromSourceNode as part of this method, and it's not applicable to NodeInstances. So, I'm just putting it here on this class.

    feature

    A string description of the feature we're trying to match. If the extractor did not produce this string, or the feature is otherwise unmatchable, we will return None.

    startFromSourceNode

    We could be given either the source node or the target node and asked to match features; this tells us which one we're trying to match.

    graph

    The graph is necessary to go from the human-readable string representation of the feature to actual edge ids.
