#2215:
- Unified the similarity and matching/equality classes under the same folder.
- Renamed SymbolicExpressionTreeNodeSimilarityComparer to SymbolicExpressionTreeNodeEqualityComparer, renamed other classes to more descriptive names.
- Removed unused classes (SymbolicDataAnalysisInternalDiversityAnalyzer.cs, SymbolicExpressionTreeMaxCommonSequenceCalculator.cs
- Renamed tests and test files.
