Support for ensemble solutions of data analysis models

Description
It should be possible to combine multiple models for a data analysis problem into a solution ensemble. For classification different voting schemes should be implemented. For regression different types of estimated values aggregation functions should be implemented.
Cross-validation should produce solution ensembles that combine the models of all folds and the training and test partitions of each model should be taken into consideration when calculating the estimated values for training and test of the ensemble solution.
