#1674

  • ProtoBuff QualityMessages
    • Changed the QualityMessage to be able to be used for single- and multi-objective problems.
    • The new SingleObjectiveQualityMessage and MultiObjectiveQualityMessage now "inherits" from QualityMessages to be able to be used in a polymorph manner.
    • This is done via protobuf's nested extensions (see http://www.indelible.org/ink/protobuf-polymorphism/).
  • EvaluationCache
    • The EvaluationCache now now stores the QualityMessage instead of a single double. This way the cache can be used for single- and multi-objective problems and additionally opens the possibility to extend the quality message with any data. (previously extended data was lost when the cache was persisted and loaded again)
    • When deserializing an older version of the cache a new single objective quality message is created from the double value. This way, no compatibility is broken and version must not be incremented.
  • Adapted the ExternalEvaluationProblem to the changes of the EvaluationCache and the QualityMessage.
  • Added a MultiObjectiveExternalEvaluationProblem on basis of the ExternalEvaluationProblem and added a IExternalEvaluationProblem interface.
