Modifying models

[cdruf]

I wonder what happens when one solves a model, changes it, and solves it again. For example, add/remove a constraint, or change the objective. In some cases, it would help to warm-start at the previous solution. Though, I guess an entirely new model is fed to the respective solver. Is there any way to keep the model and start with the old solution? Maybe via the solverModel attribute?
