Changeset 9154

#1980:

• added XCSSolution, XCSModel, XCSClassifier to represent the xcs classifier
• XCSSolution also shows the current accuracy (training and test partition has to be added)
• added XCSSolutionAnalyzer to create a XCSSolution during the run of the algorithm
• added XCSModelView to show the xcs model
• fixed a bug in XCSDeletionOperator (sometimes it deleted less classifiers than it should)
• moved some parameter from ConditionActionClassificationProblem to ConditionActionClassificationProblemData
