Message:

#1772:

• Slight refactor in QueryMatch.cs
• Added a parameter to the genealogy analyzer for removing older generations from the graph (useful to conserve memory in experiments)
• Updated wildcard nodes (added persistence & cloning)
• Implemented diversification strategy based on schema frequencies & phenotypic similarity as a separate operator (for now keep also the analyzer)
• Updated license headers
• Added QueryMatch performance test (to be expanded)
