#3026:

  • renamed ResultItem to ResultJsonItem
  • implemented RegressionProblemDataConverter
  • added support for "named matrices" (named = rows and columns have names) -> INamedMatrixJsonItem incl. base classes and views
  • added a bool property Active in IJsonItem -> marks items, which should be written into the template
