Callbacks

The Optimizer callbacks are accessed using the .NET event / delegate mechanism.
For example, to install a method OptimizerMsg of the current class as a callback to receive Optimizer messages, you must to create a MessageCallback delegate object from the function and add it to the MessageCallbacks event field of the problem: 
prob.MessageCallbacks += new MessageCallback(this.OptimizerMsg);
To remove a callback you must still create a delegate object, but use the -= operator to remove it from the event field: 
prob.MessageCallbacks -= new MessageCallback(this.OptimizerMsg);
