Interface for qp solver dependent model descriptions

The classes define the interface for obtaining a solver dependent description of the bundle subproblem. The solver has to provide (or be) a QPModelDataPointer, which generates on request (issued in ConicBundle::BundleModel::start_augmodel() ) a possibly model dependent QPModelDataObject that the model then fills with its information. Derived from this base class QPModelDataObject there is QPSumModelDataObject used by ConciBundle::SumModel and QPConeModelDataObject that is general enough to fit the models of ConicBundle::NNCModel, ConicBundle::SOCModel, ConicBundle::PSCModel, ConicBundle::BoxModel, and ConicBundle::AFTModel. The cutting model description typically consists of the collected subgradient information and the support set describing the feasible combinations of the subgradient information. A potentially present sequence of AffineFunctionTransformation instances modifies this subgradient information and the routine QPModelDataPointer::apply_aft() serves this purpose. Several classes derived from BundleProxObject also use this interface to compute the quadratic costs for the internal ConicBundle::UQPSolver. More...
