Simple example and generic function for SVM binary classifier for general matrix

Simple generic function that takes two labelled classes and trains SVM classifier (general matrix).

Simple generic function that takes two labelled classes and trains binary SVM classifier. Has very basic example code to call SVM classifier and train SVM on labelled data (returns the trained SVM as a structure). Based on code from the mathworks website and matlab documentation. Takes a general matrix by downloading spam data from UCI repository.
