Ruby Minimal Stemmer Implementation

Implements the "S-Stemmer" from How Effective Is Suffixing? Donna Harman. Just like Lucene's EnglishMinimalStemmer.

gem install minimal_stemmer

require 'minimal_stemmer'

MinimalStemmer.stem('words')
# => 'word'

It's also possible to include it so it adds a #stem method to the core ruby string method. For safety, this must be included explicitly:

require 'minimal_stemmer/core_ext/string'

'words'.stem
# => 'word'
