Message:

#1980:

• fixed several bugs (crossover, subsumption, serialization etc.)
• added ModuloOperator
• CombinedIntegerVectorClassificationProblem\Data and VariableVectorClassificationProblem\Data inherit from ConditionActionClassificationProblem\Data
• it can now be set how often the analyzers have to be executed
• VariableVectorAction, VariableVectorCondition and VariableVectorInput now inherit from Item
