#1772: Performance improvement changes

• QueryMatch.cs: eliminate unnecessary ToList() call and expensive GetBranchLevel calls
• Diversification: eliminated creation of shallow copies of the individual subscopes as it was either too slow (due to events being registered/deregistered when variables are added to the scope) or too leaky (if attempting to clear the scopes without clearing the variables then the code is leaking EventHandlers)
• Aggregated diversification statistics separately with the help of some parameters set up in the SchemaCreator and SchemaEvaluator
• Made code in the UpdateEstimatedValuesOperator perform exactly as in the evaluator (updating quality and estimated values)
• Removed no longer needed SchemaCleanupOperator
• Do not evaluate intermediate vertices in the genealogy analyzer if the TrimOlderGenerations flag is activated

New functionality:

• parameter to control the fraction of the population to be considered by the diversification strategy
• parameter to control whether individuals may be matched by any schema and mutated only once (exclusive matching)
• parameter to control whether linear scaling should be applied to the estimated values used for the calculation of phenotypic similarity (default: yes)
