Abstract base class for all splitting types. Takes a CLabels instance and generates a desired number of subsets which are being accessed by their indices via the method generate_subset_indices(...).
When being extended, the abstract method build_subsets() has to be implemented AND to be called in the constructor of sub-classes. Implementations have to fill the DynArray<index_t> elements in the (inherited) m_subset_indices variable. Note that these elements are already created by the constructor of this class - they just have to be filled. Every element represents one index subset.

Abstract method. Has to fill the elements of the m_subset_indices variable with concrete indices. Note that CDynamicArray<index_t> instances for every subset are created in the constructor of this class - they just have to be filled.
Implemented in CStratifiedCrossValidationSplitting.
generates a newly created SGVector<index_t> with indices of the subset with the desired index

generates a newly created SGVector<index_t> with inverse indices of the subset with the desired index. inverse here means all other indices.
