PorterStemmer class

A word stemmer based on the Porter stemming algorithm. Porter, M. "An algorithm for suffix stripping." Program 14.3 (1980): 130-137.

See http://www.tartarus.org/~martin/PorterStemmer/ for the homepage of the algorithm.

Martin Porter has endorsed several modifications to the Porter algorithm since writing his original paper, and those extensions are included in the implementations on his website. Additionally, others have proposed further improvements to the algorithm, including NLTK contributors.

This implementation includes further improvements devised by NLTK contributors or taken from other modified implementations found on the web.
