#1784:

• deleted not needed Consumer in ProblemInstanceProvider and IProblemInstanceProvider
• changed protection level of exporter and consumer in ProblemInstanceProviderViewGeneric
• renamed property FileExtension to FileName in ResourceClassificationInstanceProvider and ResourceRegressionInstanceProvider
• deleted ImportProblemDataFromFile method from IDataAnalysisProblem and all classes and interfaces, which implement this method
• removed unnecessary yield return in GetDoubleValues in the Dataset. Now it's a normal return statement
