Name RiStemmer
Description A simple set of stemmers for extracting base roots from a word by removing prefixes and suffixes. For example, the words 'run', 'runs', and 'running' all have "run" as their stem.
    String[] tests = { "run", "runs", "running" };
    RiStemmer stem = new RiStemmer(this);
    for (int i = 0; i < tests.length; i++)
      System.out.println(stem.stem(tests[i]));
This class provides a # of implementations, each specified by a type constant.
For example, to use the Lancaster (or Paice-Husk) algorithm instead of the Porter (the default), create the stemmer as follows: 
 RiStemmer stem = new RiStemmer(this, LANCASTER_STEMMER);

Methods
stem()   Extracts base roots from a word by lower-casing it, then removing prefixes and suffixes. For example, the words 'run', 'runs', 'ran', and 'running' all have "run" as their stem.
