@guru5590 these changes have been made. I have removed Classifier class since its no longer required. Classpath changes are also made. Please check.

@divyasrinivasan1986 , thanks for making the changes. From my side, I'll accept this pull request.

But we should defnitely look at improving the model. For instance, using stop word removal, removing the skewing based on the number of occurrences of the same word. Also, if possible consider the using the POS tagging of words for better classification along with the SVM classifier.
