The function Cut::getCuts uses the function Cut::createIloRange to translate vector<CutReturn> into vector<IloRange> such that the valid inequalities can be used by CPLEX. We should also add a function that translates our CutReturn objects into objects that can be used by Gurobi.

Do not forget to update the wiki page that describes how to use another solver as this now explains how to use Gurobi.

The function Cut::getCuts now returns a vector of CPLEX cuts. If one wants to use Gurobi, then one has to edit the function Cut::getCuts because 1) we need another return type, and 2) we have to call Cut::createGurobiConstraint instead of Cut::createIloRange.

We may avoid this by making Cut::getCuts a template function with two specialized template values (i.e., CPLEX and Gurobi). To avoid that the new template function breaks with the current code we can set the default value of the template to CPLEX.

The function will then be called as

auto const cuts = cut_ptr->getCuts<CPLEX>(model.d_env, model.d_x, x_val, true);
