#3026

  • removed property ConvertableType from all converters
  • removed the option to fixate or loosen the path of JsonItems (obsolete)
  • added a abstract formatter SymbolicRegressionSolutionFormatterBase as base formatter for ISymbolicRegressionSolution
  • unified the construction of exporter controls
  • code cleanup
