#1772: Separated tree distance calculations in different classes which implement a new interface called IDistanceCalculator. The isomorphic tree distance calculates the distance based on the maximum common subtree between two symbolic expression trees, and the bottom-up tree distance returns a value based on the number of matching pairs of nodes in a bottom-up mapping. Introduced the distance calculator as a parameter in the SimilarityCalculator operator so that the diversity analyzer can use either of the two distances.
