Message:

#1772: Fix plugin dependencies. Small changes to the SchemaEvaluator: require a minimum of 2 matches for each schema (regardless of the MinimumSchemaFrequency) and use Math.Floor instead of Math.Round when determining the number of individuals to be replaced according to the ReplacementRatio.
