Message:

#1772: - Added a ViewHost in the right side of the GenealogyGraphView which displays the encoding-specific content when a GenealogyGraphNode is clicked.

• Migrated new SymbolicExpressionTreeChart (drawing the tree using the ReingoldTilfordLayoutEngine) to the new branch
• Copied SymbolicDataAnalysisExpressionTreeMatching.cs and SymbolicDataAnalysisExpressionTreeSimilarityCalculator.cs to the new branch

Location:
