NLP management methods.
In NLP management, we have to distinguish between the current NLP and the NLPI problem stored in the NLP solver. All NLP methods affect the current NLP only. Before solving the current NLP with the NLP solver, the NLP solvers data has to be updated to the current NLP with a call to SCIPnlpFlush().
