Update sentenceParser.py

I have commented out the make frequency file because you need to first download the brown corpus .txt files
    this is easier if you use import nltk.corpus.brown(). I just have not implemented it with this functionallity
    this project was more for understanding how nltk taggs its words and trying to implement my own version of it
    Just use the frequency table file I have here and have it in the same directory as the .py
