Keep track of the SVM probability score

[marfox]

You should first locate the class where libsvm is used.
Then, you should activate the flag for computing the probability score (if not already done).
Finally, you should store it at classification runtime.

I always get a probability of 0.0 for all the classes (straight output from svm_predict_probability)
@marfox can you confirm?

As it turned out -b 1 needs to be provided to svm-train to enable probability the computation during classification. (see the libsvm page)
