 * @author Tobias Fischer
 * @author Marc Pfetsch
 *
 * We separate disjunctive cuts for two term disjunctions of the form \f$x_1 = 0 \vee x_2 = 0\f$. They can be generated
 * directly from the simplex tableau. For further information, we refer to@n
 * "A complementarity-based partitioning and disjunctive cut algorithm for mathematical programming problems with
 * equilibrium constraints"@n
 * Júdice, J.J., Sherali, H.D., Ribeiro, I.M., Faustino, A.M., Journal of Global Optimization 36(1), 89–114 (2006)
 *
 * Cut coefficients belonging to integer variables can be strengthened by the 'monoidal cut strengthening' procedure, see@n
 * "Strengthening cuts for mixed integer programs"@n
