#2215: Fixed a couple of bugs in the BottomUpSimilarityCalculator:

  • the child sequences of matching nodes were not sorted in the same way (one was using StringComparison.Ordinal, the other the default)
  • when creating the mapping it is necessary to walk the nodes of the first tree in decreasing height order (not level-order as the author claims)

#2215: Fixed incorrect namespace of the BottomUpSimilarityCalculator. Changed signature of ComputeBottomMapping method to take tree nodes as arguments rather than trees, because we should be able to compute the bottom-up distance for any two subtrees. Added internal diversity calculator based on the bottom-up distance, which computes the average diversity of all the nodes inside a tree individual.
