POS Tag for rest of words in Sentence

Takes string as input and gives the most probable POS tag for the rest of the words in the sentence.
It checks :
1) the probability of each tag for the word based on the tag for that word in the training data
2) the probability of each tag for the word based on the tag of the word before it, comparing with training data

And multiplies the two to give the most probable tag for the word.
Thus, even if you spring it a new noun, it will likely tag the word after an article as a noun.
