Matcher

abstract class Matcher extends Serializable

A matcher provides methods to process two types of inputs either a RDD[Set[Row]] or RDD[(Row,Row)]. Accordingly, we provide the "selfCartesianProduct" method to help with the conversion. There are some matchers that are asynchronous, for these we require that the onReceiveNewMatches is set. This is a function that takes some action based on new results.
