This class encapsulates logic to instantiate, use and amend stemmers for different languages. Plugin selection behavior per language is as follows: if a valid Hunspell affix and dictionary file is found in the /dev/hunspell subdirectory of your installation location (either named [language code]_*.aff or in a subdirectory named after the language code), a <class>HunspellStemmer</class> object will be instantiated to treat stemming requests for that language. If no such library is found, the corresponding <class>TextStemmer</class> will be instantiated.
If the <method>StemWord</method> method is invoked for a particular language, this class will first look up the supplied string in the list of exceptions. If no exceptions are found (either default exceptions supplied with iKnow or custom exceptions in the <class>Rule</class> table for this namespace), the StemWord method of the instantiated Stemmer plugin object will be invoked. If the plugin supports returning multiple results, these will be filtered and only the first result satisfying the corresponding rules (stored in the iKnow language model or the <class>Rule</class>) will be returned.

Retrieves a set of rules to customize or overrule plugin output, based on default rules.
returned by <method>GetDefaultRules</method> and the content of the <class>iKnow.Stemming.Rule</class> table. Any result retrieved by a plugin will have to pass these rules (where applicable) or it will not be returned. Note that this may result in no results to be passed back at all!

Starting point for advanced resolution of hunspell stemming results.
Stems pToken using pStemmer by testing it first in the capitalization supplied initially and then with initcaps and all-caps in case no stem was found. Relays to <method>StemWordHunspellRules</method> for the actual stemming.
