Numerical Corrections

K_Best_SVM now contains svm and logistic regression code to pick best
features.
PCA Testing now uses updated training data (now contains almost all
categories enteries), and the tfidf strips the stop words also
notext results contains the final figures of notext model. This has
results for logistic model for prediction and for both logistic or SVM
model for selection of features. The results don't differ  much,
although the number of features is more for SVM.
