Reimplement using Shark KMeans composite application.
Implement KMeansClassification as a composite application using an existing training and classification application.
The SharkKMeans model is used instead of ITK classes.

The applications pipeline for this composite application is :
ImageEnveloppe => PolygonClassStatistics => SampleSelection => SamplesExtraction => TrainVectorClassifier => ImageClassifier.
Use this application for:
- ImageEnveloppe: create an image envelope,
- PolygonClassStatistics : create the statistics,
- SampleSelection : select the samples by constant strategy in the shapefile,
- SamplesExtraction : extract the samples descriptors,
- TrainVectorClassifier : train the model,
- ImageClassifier: performs the classification of the input image according to a model file.
The parameters of the internal applications have been initialized such as:
The rest of the settings are by default.
List remaining open issues if any, and additional notes.
