Trains a Weka model using functionality of Fijis Trainable Weka Segmentation plugin.
It takes a 3D feature stack (e.g. first plane original image, second plane blurred, third plane edge image)and trains a Weka model. This model will be saved to disc. The given groundTruth image is supposed to be a label map where pixels with value 1 represent class 1, pixels with value 2 represent class 2 and so on. Pixels with value 0 will be ignored for training.
