Class for managing individual folds in cross-validation.
It is often desired to print/save informations that occur during individual folds in cross-validation, such as indices, parameters of underlying machine etc. This abstract base class might be called from the CCrossValidation class after each fold in order to collect these things. Different implementations then could output the informations, or even store them to make them accessible later. Since is different for every underlying machine, individual sub-classes have to handle this separately. When writing new subclasses, try to make the design as inheritance based as possible, such that future sub-sub-classes can use yours. Note that subclasses only need to implement methods that they need since all methods in this class are already implemented empty, except for num/fold stuff. These number of runs/folds and their current indices are stored since these might be used from many subclasses.
