New Features

• Model::get_var_reduced_cost was created and returns, when applicable, the reduced cost of a variable.
• Robust::ColumnAndConstraintGeneration can solve two-stage robust problems with bilevel solver for separation and trust-region stabilization.
• Mosek wrapper now handles rotataed quadratic cone conversions.
• Universal calback can now be added to Mosek (with features limited by Mosek's own calbacks however, i.e., one cannot add cuts in callbacks).
• Universal callbacks now have methods best_obj, best_bound and terminate.

Fix

• Timer was not working on MacOs.
• dualize was not handling products correctly if required to land in variable space.
• Remove warning if idol is not linked with coin-or/Osi.
• Gurobi::read was not reading the objective sense.
• Default value for "obj bound" and "obj limit" for maximization problems were set to -Inf and Inf instead of Inf and -Inf.
• coin-or/MibS warpper now uses file communication and is, hence, more stable.

Updates

• All MIP related classes and functions are now moved in idol/mixed-integer-optimization.
