Memory leak in MB with ConstantLearner

[Djalel Benbouzid]

Each time the ConstantLearner is learned and not selected, it leaks the object

                if ( (constantEnergy <= energy) || ( energy != energy ) ) {
                    delete pWeakHypothesis;
                    pWeakHypothesis = pConstantWeakHypothesis;
                    energy = constantEnergy;
                }

There is no

              else {delete pConstatWeakHypothesis;}
