ENH: Add a DS fusion test using ConfusionMatrixToMassOfBelief with new inheritance of ConfusionMatrixCalculator and ConfusionMatrixMeasurements

ENH: Remove useless parameters for opencv svm classification in otbTrainMachineLearningImagesClassifier application.

ENH: Add an ImageClassificationFilter class which classifies an image using a model (derived from otbMachineLearningModel)

This classes have been gfork and static variables have been removed to avoid dl.close error in applications.
I used itykv4 version of classes to do the fork.
Forked classes are only use in the BinaryMorphological applications. It is still the internal itkv3
which is used in OTB.
Need to report this problem to ITK in JIRA, when the problem is solve on the ITK side we would safely remove these classes and use ITK classes

ENH: Modification of the template of the ConfusionMatrixToMassOfBelief class and its corresponding tests

ENH: Using the ConfusionMatrixMeasurements class into ConfusionMatrixCalculator to compute the measurements
